Hit this recently opened spot today and was happy to find another "order off the menu" dim sum place, so that makes 3 I know of including Gitlo's and Chung Shing Yuan. I prefer the "order off the menu" type of dim sum place because food generally arrives at your table warm instead of being pushed around on a cart for a while, but the negative is you don't get the instant satisfaction of a pushcart dimsum place (wait time wasn't too bad though).
This place occupies the old Noodle Alcove place with a much brighter looking renovation (the old place was a bit dumpy and dark). It was opened by a few waiters and cooks from China Pearl across the street and isn't that busy yet. Size-wise, it's about 30-40% bigger than Gitlo which is the size of the typical hole in the wall. The place isn't large, but it's fairly cozy.
We tried out nearly 2/3 of the menu (I overordered as usual when I hit a new place :-). They have a dim sum menu and larger items menu. We ended up at $54 for 4 people, so it still wasn't too bad.
Favorites: the fried daikon cake w/ noodles (more XO sauce and daikon/sausage taste in the cake chunks than Gitlo's but the chunks are mushier), the shanghai noodles (the square slightly chewy noodles that reminded me of Noodle Alcove's noodles), lotus wrapped sticky rice (more filling than China Pearl's version), the dumpling in soup (picture one huge 3-4" diameter wanton in a single serving soup bowl), and my single favorite was the crabmeat soup dumplings (not as much soup as the traditional soup dumpling from NYC/Toronto but much tastier meat)
Misses: congee was a bit bland (but most is unless I make it w/ my sage rubbed turkey remnants), fung goh (too much veggies..China Pearl version is better), shiu mai (too much fatty pork flavor?), har gao and other dumplings (thinner wrapper than I've seen at places in the Boston area and more chives but not as much shrimp taste as Gitlo's)
I've attached a few pics of what ended up in my stomach ;-)
