3.5-4*, rounded up for being better than I was expecting!
Review is for all-day dim sum. You may have to ask for the ds menu after peak hours. I cannot comment on their dinner menu, but apparently it is not as good. It was quite quiet on a Thursday evening. Only a few tables were occupied.
I cannot remember the name of the Chinese restaurant that JAM took over, but new owners have repainted and in general, interior looks renewed. I saw a familiar face, either the assistant manager or the manager of Summit Gardens. So you can ensure they know what they're doing. Neither food nor staff are "green".
Food was good, nothing too greasy, but as per each post-dim sum, I did feel like I needed a walk. Bean Curd rolls, shrimp/chive dumplings were a couple of some better dishes. Would not hesitate to go back for either dim sum &/or dinner!
