Just got back from dinner at Trimurti after reading a number of recommendations on this board.
I have to say, it was great. I took a friend who is a big Indian food fan, as well as my parents, and everyone enjoyed the food immensely. Decent, friendly service, excellent food, and ordering from the ala carte menu we ended up at $90 with tip for dinner for four. Not too bad for downtown Toronto.
If you're looking for a delicious Indian meal (ala carte, I can't speak to the buffet) in downtown Toronto this is a great pick.
