This is the only dim sum I've experienced in Cleveland but have visited many in NYC, SFO and up and down the coasts.
That said, it's fairly authentic and therefore a pretty good choice. They use carts which I prefer because the food comes fast and furious. A good selection of just about everything with few exceptions. Fresh fish in the tanks and a small butcher area for take out pork, chicken, duck, etc.
It's a decent sized restaurant so you're almost always guaranteed a table or a very short wait. Parking can fill up but the main street provides easy alternatives to the lot.
The restaurant is in a strip mall of sorts that's connected to some souvenir shops, small businesses and the Park To Shop Asian grocery. Visiting each of these after our meal and loading up on low cost groceries at PTS has become a ritual.
Allocate a few hours and you'll have a great time.
