First off, this place needs new signage - it looks like a cheap old internet cafe.
C'est What has a good beer selection which is great. But...unfortunately the food isn't so great. I had the vegetarian roti which was basically just half-boiled potatoes wrapped in a roti. Not satisfying at all.
I'm not opposed to going back but certainly won't recommend it or go back on my own will. If someone recommends it for the beer menu and I'm in the area, then maybe I'll stop by. You can do better though in TO.
