I've been to a few supper clubs. Thought you might be interested.
Katherine (@mustardseedcook on Twitter) runs occasional supper clubs from her home.
A supper club is an occasion in which one opens one's house up to people willing to pay for your cooking.
The most recent one I've attended at Katherine's house had a Mexican theme. I booked, in advance, with friends. Other people also booked and we all turned up hungry with BYO bottles in our hand on Friday evening.
Katherine starts with a theme which evolves into a menu. The price is fixed in advance, a deposit taken with payment finished after the meal.
Katherine turns one of the rooms in her house into a dining area for up to 24 people.
It's a relaxed environment where you can be with friends, or meet new people, or both.
