Venue Suggestions for Post-Conference Party

For Northern Voice, we’re planning on a conference that runs roughly 8:30 AM – 5:30 PM. In the evening, we’re going to have a little soiree. We’ve got a few ideas, but we’re curious as to what suggestions other locals had for a decent party venue. Our criteria are as follows:

• Must be able to accomodate about 100 people. We’re not sure how many people will come to the conference. Clearly all of them won’t come to the party, so we’re guessing wildly with "about 100".
• Must be able to devote space to us on a Saturday night. This is a tricky requirement, as obviously Saturday night is the busiest night of the week for most bars and restaurants. In theory we need an unpopular but still acceptably cool venue with some dedicated space for us (an "upstairs", for example).
• Must cost us nothing or very little. This shouldn’t be too much of a problem if we can guarantee them x number of extra patrons.
• Must be in walking distance of UBC Robson Square. For now, let’s call that "anywhere on the downtown peninsula".

In theory, we’d like to stick with bars and restaurants, which provide the least hassle and most flexibility. If nothing else, we’ll look into renting some space at a hotel or other venue. Where do you think we should have this event?
