Glad to have "dim sum" on this side of town instead of having to drive all the way to Chinatown. I believe the owner runs the Chang's restaurant on Decatur so he definitely has some experience under his belt.
We ordered: Siew Mai (a little bit chewy for me... I'm afraid to ask what else is in the stuffing besides pork... yikes!), har gow (shrimp was good but the dumplings must have been in the steamer too long because the wrappers on the bottom were all torned up), Feng Zhao (a.k.a. phoenix claws or chicken feet -- good sauce/quite tasty), tripe (yummy ginger sauce), Tan tart (custard tart-- yum!) and Lo Mai Gai (Lotus Leaf Wraps)... which I thought was the best of all the dishes. The wrap came in a smaller size than what you would expect but it was stuffed with mushroom and shredded chicken.
Service here is a notch better than what you'd get in Chinatown. Server Ray was exceptional as he was very attentive -- unlike some of the others ... we would ask them for more napkins or hot sauces; they would nod like they understood -- but never came back to check on us, except for our "buddy" Ray. It wasn't a language barrier either as I spoke Cantonese to them. :-)
Anyway... I gave East Ocean a 3-star because quite frankly, this is "as good as it gets" here in Vegas. I'm still in search of a quality dim sum place in this town so if anyone knows of one -- please do tell! (sigh)
