Hi, forgive me if my first post focuses on old bars but frequenting them was a large part of my youth...
I remember JJ Rossy's in the Granville Mall (now an art gallery I think?), Jaguars then Secretary's (now Reflections), Scoundrel's below the TD building, and finally Rosa's Cantina in the Carleton Hotel.
I'm sure there are truckloads of memories out there for drinking establishments....
