So this is a tricky one.
It's a pretty standard dim sum place on Spadina. Nothing dreadful (no visible rats), mostly decent food - served hot - once you learn how to manage the steam cart ladies.
Order from the cooking table to get awesome greens to have with the ginger garlic dipping sauce.
There is however one thing that makes it worth going to Sky Dragon above almost any other dim sum spot in Toronto. The chance to have pork soup dumplings. You know - the ones with the soup on the inside. They don't always have them - and I'm not a regular enough customer to get them on demand (though they have made a couple of squid dishes for me on request) - but it is worth going just because they might have the soup dumplings. Best I've ever had. Ever.
If the only thing they served was the soup dumplings, I'd probably rate the place higher. The cart ladies trying to convince me that cool shrimp dumplings are the bomb take down the overall rating.
