How to run a restaurant successfully

Most restaurant owners who are still going after five years will tell you the same thing. The concept was never really the hard part. It is the Tuesday in February when the dishwasher calls in sick an hour before service, the kitchen is already short, and the phone will not stop ringing. That is where restaurants actually get tested. An AI assistant can take at least one of those problems off the table before service even starts.

The gap between opening a restaurant and running one well

Most restaurant owners spend months planning the opening. The concept, the menu, the fit-out, the first few weeks of service. What gets less attention is everything that follows.

Running a restaurant well means making good decisions on limited information, usually under time pressure. Food costs creep up and you do not notice until margins are already squeezed.

Somebody leaves and half their regulars stop coming in, at least for a while. You have a stretch of bad reviews and it is only later, looking back, that you can see it happened right when you were two people short. Getting back from that takes longer than most people think it will.

The owners who handle these things well tend to watch their numbers closely, look after their team, and make sure operational noise does not eat into the time they need to actually run the business.

Getting the finances under control

A restaurant that does not track its numbers will always feel like it is barely keeping up, even in a busy period. Revenue looks fine but cash is somehow always tight. That is usually a food cost or labour cost problem that has been invisible for too long.

Food cost should generally sit between 28% and 35% of revenue. Labour cost between 30% and 35%. When both are at the top of those ranges at the same time, there is not much left. Most restaurant owners know this in theory but do not have a system that tells them where they actually are on any given week.

Sitting down once a week and going through what came in against what went out is genuinely enough to catch most problems before they get expensive. It does not need to be complicated. The restaurants that do this consistently find problems early. The ones that check quarterly find out about them after they have already done real damage.

Menu engineering is part of financial management

Your menu is not just what you serve. It is a financial document. Dishes with high food cost and low popularity cost you money every time they are on the pass. Dishes with low food cost and high popularity are where your margins actually come from.

A simple exercise: go through every dish and work out which ones are popular and which ones earn decent margin. The ones that are neither popular nor profitable should probably come off the menu, even if the chef likes making them.

Shorter menus are also easier to run. Less prep, less waste, less complexity for the kitchen during a busy service.

Managing staff in a sector with high turnover

Hospitality has one of the highest staff turnover rates of any industry. People leave for better hours, better pay, a better atmosphere somewhere else. Some of that is unavoidable.

The restaurants with low turnover are usually not paying significantly more than anyone else. What they are doing is not dumping management problems onto the team. Rotas that change two days before the shift, information that never gets passed on, chaos that could have been planned around if anyone had thought about it earlier. That is what drives people out.

On the practical side, rotas should be set at least two weeks out. Shifts should be predictable enough that staff can plan their lives around them. When that is not the case, the people with other options will find other options.

Reducing the interruptions that break service

One thing that does not get talked about enough is how much operational noise lands on staff during service. The phone rings and someone has to step away from the floor. A guest asks a question that requires going to find a manager. A booking needs to be adjusted and the person who can do it is mid-order with a table.

A lot of restaurants treat these interruptions as just part of the job. They are not. Each one costs something: the table that waits slightly longer, the order that goes in less carefully, the rhythm of the evening that gets broken. Over a busy service those moments add up more than most people realise.

Phone calls are the most fixable of these. A restaurant phone answering service like Bonnie handles every incoming call automatically, in 20+ languages, and connects directly to your booking system. The team stays where they should be. Setup is under 30 minutes and most places are live the following day.

Running the kitchen without it running you

The kitchen is where most of the money gets made or lost. Good food at a reasonable cost, prepared consistently, sent out at the right speed. That sounds simple and is genuinely hard to maintain over a long service.

Recipe cards are the starting point. Every dish has a standard: weight of protein, volume of sauce, plating instructions. When that standard is written down and followed, food cost is predictable and quality is consistent regardless of which chef is on. When it lives in someone’s head, you are dependent on that person being there.

Supplier relationships matter more than most owners realise when they start out. A good supplier will tell you when something is about to go up in price, or when a product is about to go out of season. That kind of information lets you adjust the menu before you have a problem rather than after.

Waste is a financial and operational problem

Food waste in restaurants is often higher than owners think. Prep waste, spoilage, over-portioning, dishes coming back largely uneaten. Each of these has a different cause and a different fix, but they all show up in the same place: your food cost percentage.

A weekly stock count tells you whether what you ordered matches what you sold. When those numbers diverge consistently, something is going wrong somewhere. Catching it early is much easier than investigating a six-month discrepancy.

Customer experience is the thing people actually remember

Guests do not write reviews about your food cost percentage. They write about whether they felt welcome, whether service was attentive without being intrusive, whether the evening went the way they hoped it would.

The basics matter for a reason. A warm welcome when someone arrives. Enough time with the menu before anyone comes to take the order. Someone checking in without hovering. These things are not difficult and they are not expensive. They just require the team to be present and not distracted.

Regulars are worth protecting. A guest who comes twice a month and brings different people each time is more valuable to the business than any amount of walk-ins. Knowing their name, remembering something about them, making them feel like the restaurant notices them. It costs nothing and builds loyalty that is very hard for a competitor to take away.

Handling negative reviews without making them worse

A bad review handled well can actually build more trust than a good one. Guests reading your responses can see whether you are defensive or whether you take feedback seriously. A short, genuine reply that acknowledges the problem and says what you are doing about it is almost always the right move.

Arguing, making excuses, or ignoring the review entirely all tend to confirm whatever the guest said.

Marketing that does not require a full-time job

Google Business Profile is the most important thing to get right. It shows up when people search for restaurants nearby, shows your hours and photos and reviews, and it is free. Keeping it accurate and responding to reviews there is worth more than most paid advertising.

Instagram works well for restaurants that have something visual to show. A dish that photographs well, a kitchen you are proud of, a view from the terrace. The restaurants that do this well post consistently and do not overthink it. One or two decent photos a week is enough.

Email is underused. A simple list of guests who have opted in, a message every few weeks about what is new on the menu or an upcoming event. The conversion rate from email to reservation is significantly higher than from social media, mostly because the audience has already expressed interest.

The operational things that quietly drain time

A lot of what makes running a restaurant hard is not any single big problem. It is the accumulation of small ones. The booking that was taken over the phone and never made it into the system. The supplier who delivered short and someone forgot to flag it. The staff member who did not know about a menu change because nobody told them before service.

These are process problems. Most of them are solvable with simple habits that get consistently followed. A five-minute pre-service briefing. A shared log for delivery issues. A booking system that every reservation goes through, rather than some into a notebook and some into the software.

The restaurants that run smoothly are not necessarily the ones with the most talented people. They are the ones where the basics are handled consistently enough that energy can go into the parts that actually require skill.

How Bonnie fits into daily restaurant operations

One area where a lot of restaurants lose time and money without realising it is the phone. Calls come in during service, during prep, during the hours before opening when there are ten other things happening. Some get answered. Some go to voicemail. Some just ring out.

35% of restaurant calls go unanswered on average. At €50 a cover, that adds up quickly.

Bonnie is a restaurant phone answering service that picks up every incoming call automatically. It connects to Formitable, Zenchef, TheFork and other booking systems so reservations go straight into your calendar without anyone entering them manually. It handles calls in 20+ languages and sends WhatsApp confirmations to guests automatically.

Setup takes less than 30 minutes. Most restaurants are live the following day.

All plans include a 7-day free trial with full access. Annual billing is 10% cheaper.

Frequently asked questions

What does it actually take to run a restaurant successfully?

Consistency, mostly. The restaurants that survive long term are not necessarily the most creative or the best located. They manage food cost and labour cost carefully, look after their staff well enough to keep them, and give guests a reason to come back. The concept matters less than the execution of it over hundreds of services.

What is the biggest reason restaurants fail?

Cash flow problems, usually. Not running out of customers, but running out of cash while waiting for revenue to arrive. Food cost and labour cost that are too high relative to revenue, often because the owner did not have clear visibility on the numbers until the damage was already done. Catching those things early, through weekly rather than monthly reviews, is what separates the restaurants that survive a difficult period from the ones that do not.

How do you handle staff turnover in hospitality?

You cannot eliminate it entirely. What you can do is not make it worse. Clear rotas set well in advance, a management style that does not pile operational chaos onto the team, and making people feel like they are part of something rather than just filling a shift. The restaurants with the lowest turnover tend to be the ones where the working conditions are predictable and the management is straight with people.

How do you improve customer experience without spending a lot?

Start with the basics. A proper greeting when guests arrive. Enough time with the menu before anyone comes to take the order. Staff who are present without being intrusive. These cost nothing. Beyond that, the highest-return investment is usually removing the things that frustrate guests: long waits because someone was on the phone, a booking that did not make it into the system, a question that nobody could answer. Fixing the operational gaps has more impact on the experience than most decoration or PR.

How does a phone answering service help run a restaurant?

It removes one of the most common interruptions during service. When the phone is handled automatically, staff on the floor stay focused on the guests in front of them. Bookings get taken even when the restaurant is at full capacity or closed. For most restaurants, the number of calls that go unanswered during a busy evening is higher than the owner realises until they actually measure it.
