Toronto is highly multicultural. We have a Chintown, Little Italy, Greek town, etc etc . My wife and son are hitting a New Orleans influenced place tomorrow before a show? When you are a foodie like me , there is an endless supply of places to eat. I believe there are close to 20,000 of them. Pricing varies...you can get a great steak sammy for $15 or a $1000 Wagu steak.
The airport area is ok, has some decent places to go but you should definitely try and get a weekend and explore the downtown entertinment district , distillery area , and others. With the US$ being at a 30% premium you get a nice break. If you ever do, give me a heads up , would be happy to show you around.
