I have lived in TO for a long time. There are godzillions of restaurants, and a great many great restaurants. But it all depends on what you like to eat, whether decor and ambiance are critical for you, how much you want to spend, whether your life revolves around food (i.e. how far you are willing to travel for an interesting dining experience), are you interested to try new things, etc. This is a VERY cosmopolitan city. Some of the most interesting places (IMO) are outside of the city, although some are inside. You have lots of good choices, but you need to give us some clues about what you want to eat.
