Canoe, 54th floor of the east TD center tower on wellington street... did the whole girlfriend fancy dinner thing there last year. I'm not too sure that I recal the menu being veggie-friendly or not.
I admit the reason we partially decided to go there was because of the Yukon Caribou steak being the first item on the menu, and a window seat on the 54th floor of a tower is almost as good as eating in the CN without the rotating.......it was about a $175 meal plus cocktails for the 2 of us. Keep in mind this was a proper 3 course meal with desert and wine.

edit: eyefloater totally just beat me to it
