Dim-sum in Northampton MA!
The venerable Hunan Gourmet has just introduced dim sum daily 11-3. They are serving now from a menu of about 35 items but promise cart table service when it gets busier. Everything we tried was fresh and hot if not particularly distinctive. In general their food is very good so I'm hoping dim-sum catches on in NOHO so they'll start dishing out some more imaginative "little hearts."
Great Wall has dimsum only on Saturdays, very tasty and distinctive but rather limited choice. Also, we've been there a half dozen times and still find the service to be inscrutable, i.e. some carts, some buffet, some menu, and two delightful young boys (under 12) who, I think, keep track of what you've ordered/eaten. Everyone is very friendly, and it's impossible not to like the place.
I love the adventure of dimsum and miss the Dim Sum off New Britain Ave. in Hartford. I hope both of the dim sums in Noho/Flo prosper mightily.
