This page is about the two formats rather than about particular hosts or brands, because supper clubs are individual people cooking and naming one would tell you nothing about the next.
What a supper club is
Somebody cooks for paying guests in a space that is not a restaurant: a home, a railway arch, a hired room above a pub. You buy a ticket for a named date. The menu is fixed and usually set by whatever the host is excited about. Seating is decided by the host, often long tables, and the other guests are whoever else bought a ticket.
The good version of this is very good. You get cooking nobody would put on a restaurant menu, at a price that is often below what the same food would cost in a dining room, in a room with some atmosphere to it. The food is the reason to go and the company is a bonus.
Three practical things follow from it being an event. Popular sittings sell out weeks ahead. There is no next week unless you go and find the next one. And because the host is one person, cancellations happen and there is no second table to move you to.
What a dinner club is
A dinner club is a recurring seat. Somebody else decides the restaurant, fills the table and tells you where to be. You are buying the arrangement rather than the meal, and you pay for your own food when you get there.
The good version of this is also very good, but it is good at something different. It runs to a pattern, so there is always a next one. It is the same commitment every time, so booking takes a minute rather than an evening of research. And because the table is assembled rather than self-selected, you end up sitting with people you would never have picked, which is the entire point and also the part people are nervous about.
The trade-off is the food. A dinner club books a restaurant that can seat six on a weeknight and get them fed, which is a sensible restaurant rather than a remarkable one.
The honest way to choose
Ask what the evening is for.
If you want to eat something memorable, a supper club wins and it is not close. Nothing assembled around a restaurant table will beat a person cooking one menu for twenty people who chose to be there.
If you want the evening to exist at all, a dinner club wins. This is the case that goes unsaid. The reason most people in London for work eat alone is not that they cannot find a supper club, it is that finding one, choosing a date, and committing three weeks ahead is four decisions, and at half past six in a hotel room the cost of four decisions is higher than the cost of room service. A standing weekly pattern removes three of them.
If your diary firms up on the Monday, a supper club is close to unusable and that is nobody's fault. Tickets for good ones go early. A dinner club that runs the same nights every week is the format built for exactly this problem.
If you want to go with somebody, a supper club is easier. A matched table is for turning up by yourself, and bringing a colleague to one defeats the object.
Where KF.Social sits, in full
We run the second kind, in London only, and since this page holds the formats to detail, here is ours.
Tuesday, Wednesday and Thursday, sitting at 19:00, in Soho, Shoreditch and Clapham. A table is laid for six, and a seventh booking is not turned away: another table of six opens rather than anyone being refused. It is 15 pounds for the seat, shown before you pay, and you pay for your own food and drinks at the restaurant. No subscription. Booking gates on being 18 or over and on paying, and on nothing else.
Booking closes six hours before the sitting, which is also when you are told the restaurant. Who you are sitting with lands an hour before, with the group chat. Whether the table runs is decided three hours before against a floor of four seats, and if it does not reach four it does not run and everybody is refunded in full.
Cancelling has three rungs. Outside 72 hours the 15 pounds returns to your card. Between 72 and 24 hours it returns as KF Points, credit toward a later dinner at 1,000 points to the pound. Inside 24 hours it does not return, because by then the table has been built around you.
The table itself is assembled rather than drawn out of a hat. Anyone you have asked to avoid is never seated with you, and that one is absolute. After that we build for shared interests, close age bands and a balanced room, and we push hard against seating you with people you have already met or sending you to a restaurant you have already eaten at.
Can you do both?
Yes, and on a long stay it is the sensible answer. Book the supper club for the Saturday you know about a month out, and use a dinner club for the Wednesday you did not know about until Monday. They are not competing for the same evening.
