First off, The Portside Pub (7 Alexander Street in Gastown) has recently started a weekly quiz, Wednesday at 8PM. Highlights include free canapés during the quiz, and a pair of Canucks tickets as a grand prize. That's some quizmaster largesse right there. I'll try to get a review up in the next month or so.
Secondly, the Biltmore will be putting on the one-time event "Harry Potter and the Hall Of Inebriation" on Wednesday (when else?), January 21st. Tickets run eight dollars apiece, Butterbeer and Firewhiskey will be served, and the ultimate Harry Potter trivia master will be determined. We're a long way from Hogwarts, so this might be your best chance to nab a Nimbus 2000, Sorting Hat, or Time-Turner.
