I'm thinking of organizing a tweetup for Vancouver Librarians and information professionals, but I have no idea what venues around town would be open to such a thing. Can you recommend a few places that have been home to successful tweetups, and provide contact information for the venue if you have it?
The number of attendees and nature of the event will affect what venue is best.
Doolins, Ceilis, Yaletown Brew Pub, are all great if your crowd is into having a few beverages and socializing in a moderately loud atmosphere.
If you wanted something a bit quieter less pub like then you might try ING Direct and see if you can book their boardroom (for free) you can tweet @meenasandhu from ING.
We have a great lounge area at Pourhouse in Gastown with a nice big bar that could facilitate tweetups. @pourhouse_van. http://www.pourhousevancouver.com
