In general, I am underwhelmed by the food in Chinatown Toronto. I find the Chinese food in the suburbs (Mississauga, Markham, & Richmond) to be tastier.
I had dinner at House of Gourmet two nights ago. A plus is that they are open til late (2am/4am). Their appetizer selection was lacking. It's a Cantonese restaurant with roast meats, is clean, and does have non-Canto dishes.
I tried a Sichuan-style spicy eggplant with minced pork, which was just okay. I wasn't craving anything Cantonese at the time.
