Bar / restaurant in Belfast that will cater for group of 30-40 people?

I need to organise a get-together in the Belfast area for a group of 30-40 people on a Friday night. Is there somewhere that say has a private room or area that we could have without excessive cost? We would like something to eat and then be able to stay on there. We also would like to be able to have conversation over dinner so no loud music, but once we have finished eating, we'd like a wee boogie. Can you recommend anywhere?

I agree with JC - Budda or Benedicts would probably be a good choice. Wouldn't recommend Madisons as I find it a bit rowdy, and Ten Square is not good if you fancy a meal and conversation as the accoustics are terrible in it and you can't hear the person sitting right next to you over all the shouting.
If you choose to go to Budda, you can stay on there afterwards as it is also a bar and club upstairs, or you can go upstairs to Bar7 or across to the Box, which are the best places to go in the Odyssey - Just be warned, the Box are very selective about who they let in and are fussy about shaved heads/tattoos etc.
I would also recommend Bourbon on great Victoria Street.

i would recomend somewhere in the odyssey arena like the budda bar they do great food roughly about 拢10 per head then on to one of the bars in the complex.
or how about maddisons in the city centre or benedicts all resonable for food and a good night out after.
there is also ten square a hotel in the city

Definitely try the Oddysey.
