SE1 party venues

I turn 30 this year and am looking for somewhere local to celebrate. Ideally I'd like to hire a room above/below a pub/bar on a Sat night, which could accommodate 30-50 people and has space for a spot of dancing.
Any suggestions gratefully received.

the Miller of Mansfield has a room as does the Roebuck-not sure how many they hold though

The Woolpack also has a room upstairs

we celebrated my sister-in-law's 30th a few years ago in the Leather Exchange, they have an upstairs room.

I'm also turning 30 this year, and am likely to be doing something similar, so i'd like recomendations too.

The Garrison - amazing food and they have a big cinema screen in their private room if that appeals. Village East for drinks afterwards now they have a 1:30am licence?

We've twice had the SE1 Christmas party in the Chaucer room upstairs at the Royal Oak. Dunno about the dancing though....

Roebuck would hold 30-50, but it always feels to me like a bit of a village hall. River Bar claims to have a downstairs function room.

The Leather Exchange has a big room upstairs and can sort out your music so that it's separate from downstairs if that is what you want.

does The Roebuck in great dover street still use upstairs?

yes, I was in there recently and someone was having a "power Ballads" party - some very funny costumes occasionaly wandering down the stairs!
