This is a great restaurant supply shop in the Queen West area. The aisles are packed from top to bottom of pots, pans, and supplies. This store nearly isn't as big as Tap Phong, but there are definitely gems to be found, if not, they can probably order it for you.
Staff help is hit and miss. Some are very helpful and will help you right away, other times I've been browsing the store for 20 mins and then someone will ask if I need anything.
If you're looking for an odd sized baking pan or some higher end cookware for cheaper (e.g. Staub), this is a good place to hit up.
