This is easily one of the best dim sum restaurants in North America. Chicken feet and steamed pork ribs are to die for. On the dessert side, they have this amazing pumpkin flavored pastry and I definitely recommend exploring the menu items if you have enough time in Toronto and/or you're going with lots of people.
Four stars only because they don't serve dim sum on carts - I know this is a weird reason but that's what dim sum is supposed to be like!
