I can't find (or, really, effectively search for) a topic for this place, so I'm starting my own. I'd like to thank everyone who's recommended this place, including the late Bux, who often spoke of his appreciation for the place on eGullet's Manhattan board, and the folks on Chowhound who've been touting Go Go's dim sum as being in the modern Hong Kong style, which they explain is lower fat compared to the 1980s Hong Kong style that is featured by the big dim sum eating halls in Chinatown (forgive me, many are touting the place but I fear I've forgotten the name of the one who explained the style of its dim sum). Now that I've tried the place out, I wonder why I waited so long.
I went there for lunch yesterday (Wednesday) with a friend, arriving around 11:50. I think one other table was occupied, but by the time we left around 1:10, the place was busy.
We had the following:
Turnip cakes (fine rendition, with finely minced strips of ham)
Roast pork bun (thin dough, very tasty filling)
Baked egg custard (another very good rendition - the crust was firm and not excessively flaky, and the filling was a lot better than one gets used to in Manhattan)
Rice rolls with shrimp (the long, thick noodle stuffed with shrimp - I found this rendition rather uninteresting, and the sauce tasted like straight soy sauce)
Chicken bun (too doughy, but the filling was tasty)
Chives and shrimp dumplings (very good and clean-tasting)
Duck dumplings (also good)
Jade dumplings (a vegetarian item which included some kind of green bean [edamame?] and I'm forgetting what else [carrot?], but it was nice)
As you can see, we had a substantial meal. The cost was something like $22 and change plus tip.
In general, I would characterize the items we had as well-made from good ingredients and relatively light, especially for dim sum. This is good Cantonese food, and I will surely return to try other items.
