This is my fav Dim Sum place in the GTA. Even though it's a bit of a drive to get here, the Dim Sum is probably the best I've had outside of Asia.
Be prepared though; the waits are NOTORIOUSLY LONG. Don't arrive hungry because you will quickly turn hangry before the meal begins. For a party of two on an average (non-weekend) day you will probably wait 30mins but groups - be prepared to wait longer.
My personal favs are the rice noodles stuffed with different ingredients such as BBQ pork and deep fried pastry. I also love how everything is made to order instead of peddled on carts because all the food arrives hot and fresh.
The price per dish a bit more than the average dim-sum joint but the larger portions make it well worth the price difference.
