Cleveland: xiao long bao (Soup Dumplings)
I've had soup dumplings at Siam Cafe. They were good. It was always as a part of a multi course prix fixe meal. They aren't on the regular menu. Someone else arranged the meals. I don't know what the restaurant's policy is. I'm sure it would at least require a call in advance, but that may be enough. I've never seen them anywhere else.
Siam cafe also has a nice beef soup with shrimp dumplings and I like their potstickers.
