Friend told me they're open now, basically at the corner of 6th and 6th downtown, right by Nanta. Not sure when grand opening is, but soft opening hours are 5pm - 9pm every day.
I always hit up the Gyu Kaku on Nelson whenever I'm in Vancouver, as well as Guu on the floor above it. Basically Gyu Kaku is Japanese BBQ, you can order a-la-carte or courses. The courses are usually a bunch of different meats, some appetizers and ice cream. $20 for a 60oz jug of Asahi or Sapporo. I think the food's great and the atmosphere's fun as well, and I'll be checking out the Calgary branch sometime this week, probably on a weekday so there's less people around.
Here's the menu and website:
