I have to agree with the existing reviews. Tomi-Kro is up there on my top of Leslieville or Toronto lists.
I've heard people call the front / church area Toronto's culinary triangle thanks to Lucien, Jamie Kennedy Wine Bar, and Colbourne Lane, but in fact between Tomi-Kro and Gio Rana's (The nose) on the same block, this area of Leslieville seems on its way to becoming a more casual and trendy rival. Yet another data point to support my claim that Toronto's future is in the East.
Amazing and unique ambiance, great good, and good service (don't remember it being standout) make it both a great date place or large party gathering.
