The Kings Head off Borough Hi Street has an upstairs room with bar - when I hired it (though was four years ago) you just paid a deposit (I remember it wasn't very much) and if, I think, over 20 people attend your deposit is returned. They could do food too - though I did my own.
Another alternative is The Hop Cellar in the Hope Exchange in Southwark Street
(London Br end)- they'll reserve an area for you and their platters are very good - as are the staff.
