To make a large group reservation that goes smoothly, settle a firm headcount and a shortlist of dates first, then phone the restaurant rather than booking online. Ask how they handle groups of your size: whether they need a set or pre-order menu, a deposit, or a minimum spend, and how the bill and any service charge will work. Collect everyone’s dietary needs before the day, confirm in writing a few days ahead, and agree with your group how the bill will be split before anyone sits down.
Here is the process step by step.
Key takeaways
- Fix a realistic headcount and two or three possible dates before you contact anywhere.
- Phone the restaurant: group bookings often have rules that online systems do not show.
- Ask about set menus, deposits, cancellation terms and how service charges are handled.
- Gather dietary needs and allergies early and pass them on in one clear list.
- Agree how the bill will be split before the meal, not at the end of it.
Step 1: Pin down the numbers and the dates
Restaurants plan staff, tables and food around group bookings, so a vague “about fifteen, maybe twenty” makes it harder for them to say yes. Send a quick message to everyone with two or three possible dates and ask for a firm reply by a set day. Count only definite yeses, and keep a short list of maybes.
Think about the shape of the evening, too. Is it a relaxed meal, a celebration with speeches, or a work dinner? A group of twelve chatting across one long table needs a different space from a group of twenty that wants to mingle.
Step 2: Shortlist restaurants that suit groups
Not every restaurant can seat a big party together. Look for places that mention groups, private or semi-private areas, or long tables. Check the menu online for range: with a large group you will almost certainly have a vegetarian or two, someone avoiding alcohol and at least one allergy.
Location matters more with a crowd. A central spot near public transport is kinder than somewhere only reachable by car, and step-free access is worth checking if anyone in the group uses a wheelchair, a walking aid or a buggy.
Step 3: Phone and ask the right questions
Online booking systems often cap party size, and even where they do not, a call gets you better information. When you ring, ask:
- Can you seat us together at one table, or across joined tables?
- Do you require a set menu or a pre-order for a group of this size?
- Is a deposit or card guarantee needed, and what is the cancellation policy?
- How long is the table ours for?
- Is a service charge added for groups, and is it optional?
- Can you produce separate bills, or only one?
On the last two points, it helps to know the rules. Acas, the UK’s workplace advice service, explains that a service charge can be voluntary or compulsory, and that the Employment (Allocation of Tips) Act 2023 covers tips, service charges and gratuities that employers control or significantly influence. The government’s statutory code of practice says the law, in force since 1 October 2024, makes it mandatory for all tips to be passed on to workers without deductions. Asking politely how the service charge works is entirely normal.

Step 4: Confirm the large group reservation in writing
Once you have agreed the details, ask for an email confirmation that covers the date, time, number of guests, any menu or pre-order deadline, deposit terms and the cancellation policy. Keep it somewhere you can find it on the night.
| What to confirm | Why it matters |
|---|---|
| Final headcount and deadline for changes | Avoids paying for no-shows |
| Menu type and pre-order date | Lets the kitchen prepare |
| Deposit and cancellation terms | No surprises if plans change |
| Table time limit | Helps you plan speeches and pudding |
| Service charge and bill arrangements | Prevents end-of-night confusion |
Step 5: Collect dietary needs and allergies
Ask everyone for allergies and dietary requirements when they confirm attendance, not the week before. Pass these to the restaurant as one clear list with names, so the right plate reaches the right person.
In the UK, GOV.UK’s guidance for diners notes that restaurants must give you accurate information about allergens, and suggests calling ahead to ask how food is handled in the kitchen. For a guest with a serious allergy, encourage them to speak to the restaurant directly as well; they know their needs best.
Step 6: Agree on the bill before the night
Money causes more awkwardness at group dinners than anything else. Decide in advance whether you will split evenly, pay for what each person orders, or have one person pay and others transfer their share. Tell everyone when you confirm the booking. If a set menu applies, sharing the per-head arrangement early means nobody is surprised.
On the night, arrive a little early, check the table layout, and be the person the staff can talk to. That one point of contact makes service smoother for everyone.
Frequently asked questions
How far ahead should I book for a large group?
As early as you reasonably can, especially for weekends and the run-up to holidays. Larger groups need more planning from the restaurant, and popular places fill their bigger tables first.
Why do restaurants ask large groups to pre-order?
Cooking many different dishes at once for one table is hard for a kitchen. A pre-order or set menu lets them prepare, so all the plates arrive together and the meal does not drag.
What happens if fewer people turn up?
It depends on the restaurant’s terms, which is why you should ask about deposits and cancellations when you book. Let them know about any change in numbers as soon as you can.
Before you pick up the phone
Make a short list on paper: headcount, dates, budget expectations for guests, dietary needs and your questions. With that in front of you, the call takes five minutes and you will sound like someone the restaurant is glad to host. If young children are coming along, our step-by-step plan for eating out with a toddler has ideas for keeping the smallest guests settled, and our guide to choosing a first date restaurant covers the noise and layout questions that matter just as much for a group.
