Belgium meeting venues?

We’ve got the next meeting of the Cognitive Edge European network coming up on 15th October in Brussels.

We’re looking for a good venue – all the hotels and meeting rooms in Brussels seem to be extortionately expensive. We want somewhere central, that’s easy to reach from the train station, can hold between 20-30 people, preferably has wi-fi (free? – there will be plenty of bloggers and twitterers…).

Any suggestions to myself or Anne, please.
