I'll be the first to admit that it took me a while to jump on the Dim Sum Dynasty bandwagon. Our early experiences there were limited to delivery, and were mediocre. At that point the dim sum menu may not have been well established, or at the very least it wasn't clear to us that dim sum is what you should order at a restaurant called "Dim Sum Dynasty."
The menu at that time, and even now to some extent, has some excellent gems interspersed with what I would consider standard Americanized Chinese dishes, albeit Americanized dishes done decently enough. I don't care about those dishes, so it did take a while to fish out the good stuff. And the bulk of the good stuff is most definitely the dim sum. Dim Sum Dynasty has some of the best dim sum that I've ever had, though I haven't had much (shhhhh...), aside from a few outstanding experiences at Chinatown Brasserie in NYC.
