Awwhh yee - this place is the shit.
Went for 12pm dim sum on a Sunday. Wait time was to be expected and we didn't get seated until 1pm for a party of 8. But that was okay. With a place this popular and no reservations, it only heightened the hunger (though this is just my optimism speaking).
Highlights: Salted egg-yolk buns (YES!), BBQ puff pastry, baked BBQ pork bun pastry (pineapple bun topping) - a lot of other dim sum places in the GTA don't have these.
Everything else was pretty standard but much better than other dim sum places. Portions were bigger, juicier, and filling. I would recommend making reservations ahead of time, especially if you're in a big group, that way you can sample and share a lot of different dishes.
Overall, would come back again :D
