Not an opening, exactly, but Joyful Garden, next to Motor Vehicles in that mall in Watertown (the one with Best Buy and Target in it) now serves dim sum on weekdays. Originally – as far as I know (and at least I know that’s not much) – it was just weekends.
Please go,
I was there last week, and the absence of crowds meant that the same offerings circulated over and over. Despite that, much of what I had was decent: soup dumplings, shrimp dumplings, rice-in-lotus-leaf, etc. They have chicken feet, tripe, etc., ergo they need to be supported. Where else will you get a chicken foot in Watertown?
