I liked 'The Ski Stop'... it's kinda hidden though... Glacier is good. Not a real fan of Monods, too big. A good place for a premiere? That's simple, Wild Bills! I went to a show of (premiere apparently) TGR: High Life there last year and it was dope. They have a great screen there and a wicked environment when shows are on. IMO, the best place in Banff to have a premiere that is easy to get to. The only other good place would be The Rose and Crown but it's too small (the room with the screen) there and they don't have a big screen...
Go big or go home
