Christmas Party - idea needed (Brussels)

Dear All,,
I have to prepare a Christmas Paty for about 40 people from our department.
Usually we go for dinner and have some self-invented activities.
However this time I am searching for an alternative way of spending this time than having "team building" activities.
Of cours meal need to take a place but if we would have any interesting entertimet - that would be something!
I was thinking about the Warehouse Studio Theatre but it seems to be not available.
Any ideas?
I can add that it has to be sth in English if the language skills matter.
I would appreciate any suggestion:)
