I try to visit Fionn's almost every time I make a trip to Toronto. My first visit was probably in 2001 or 2002 and it's been consistently great every time.
Everything I've eaten has been tasty (mostly from the late night menu) and the bartenders are always super friendly. I don't usually find myself here when it's super busy on the Esplanade, but when I have I've been equally pleased.
The drinks are expensive for my tastes, but all the drinks in Toronto are to me so it isn't anything surprising.
A cool place with a good vibe on a weeknight and a really great interior. I'll continue to visit Fionn's when I'm in Toronto!
