Great beer and craftails (a cocktails made with liquor and craft beer). Bartenders are always friendly, attentive and knowledgeable. Interesting basement feel with high and low top tables, pool tables, and a fireplace. I haven't tried to food yet there because we tend to eat somewhere else and then find our way to C'est What?
The owner of C'est What? was the founder of Toronto Beer Week so it is definitely a must-go.
