London bars for a 40th/engagement party with music and canapés for 50 people xx
A friend of mine is doing something similar at Diogenes The Dog in E&C next month – lots of great wine!
The Bluebird Chelsea has a room for 50 people standing for drinks and canapes
The Maine Mayfair is an amazing venue - their ground floor room that opens into the courtyard would be fab for this! https://themainemayfair.com/
