Looking for a venue for a Halloween party for teen and her friends

[flg728]

Hi All, My 16year old wants to have a Halloween party for around 50-75 people. Does anyone know of a cheap venue/room for hire? Would like to stay in North London. Thanks!

How far north? I've been to a couple of parties at Rowley Barn Borehamwood, it's a great venue but probably not cheap. Otherwise I can only think of places like Cecil House, Hampstead Old Town Hall, room upstairs st Cafe Rouge in Hampstead, various pubs with separate rooms .....
