I just had lunch there. It's a great selection, prices sure can't be beat, everything seemed like it was well made and tasty; but everything was either cold and coagulated, cool, or at best room temperature. The pan fried dumplings were nearly inedible. The cha siu soh (baked bbq pork pastries) were also horrible. The steamed dumplings held up the best, but still... It should have all been hot, or at least warm, it was the height of lunch hour and the place was doing a brisk business.
I've been before and it has been better, although still not as good and piping hot as the best dim sum is. I'm thinking it might be best to go there, get stuff to takeaway and then reheat it at home. What sort of dim sum do you think reheats the best?
