If I wrote this review 5 years ago, it would probably get 5 stars because of the lack of large Chinese grocery stores in Mississauga. That's no longer the case with Oceans, Btrust, Yung Ming and T&T all within 10-15 minute drive of my home.
Pros: lots of dim sum, nightly specials on hot food and free samples of food during the weekend. Good Asian veggies (e.g. bok choy, Chinese broccoli, etc.).
Cons: If you find all the right flyers, you can price match at Wal-mart and Superstore and is much cheaper for day to day groceries. Also, sometimes the hot food is way too salty.
I think T&T is a good shopping experience, but not necessarily the cheapest or best variety. Also, T&T is now owned by Loblaw. Co. Ltd, so if you go to a Superstore, they sometimes have the same stuff in their ethnic situation.
