bistrotheque in hackney is a great eatery and they have burlesque nights. it's the only time I've had steak tartare and it was amazing.
Another fun place in hackney is The Camel, their pies are fantastic and they have loads of games, decor is cool too.
Plastic People on Curtain Road has some cool music events, it's a nice small friendly intimate place and a good place to get fucked up and dance.
