There are two main reasons I love Jamboree. Firstly, it's the fact that you have to go through a security gate to enter, which gives it an air of "prohibition/underground bohemia" and there's not much of that left in over developed London. Secondly, the furniture and general props are scattered around the place as if you've arrived at the aftermath of a great party and they just don't give a sh*t.
The thing is, it's kinda hipster before hipster tried too hard, boho without any pretention and effortlessly creative. As a result it draws in a great relaxed, understated, yet stylish crowd. The kind of people that you know have something interesting to say and their nights out aren't just about getting plastered.
On top of the great venue,it actually has wonderful entertainment. The Tuesday folk night involves a group of musicians sitting on a small table strumming away, giving the place a feel of someone's living room at a great, chilled out party. The swing night is like that very same party on steroids, with a live band, lots of people dancing and air of hedonism.
I've not checked out the place on other nights and I've only visited in cold weather, yet the outdoor area, in a private, cobbled, undeveloped mews definitely lends itself to some great summer nights. Join their mailing list to see what event takes your fancy - whatever the season.
