Overall for Chinese roasted meats we like C&M Bistro or New Gold Medal.
At C&M Bistro we especially like the char shiu (half lean, half fatty) and the roasted pork belly.
Roast duck is good at both places. I don’t find one much better than the other.
I really liked the roast duck from New Tin’s Market I had a while ago, but that was from a friend who knows the owners pretty well. It seemed better than ones we’ve bought ourselves in the past.
We don’t buy roast pork that often as we’re pretty picky and only like it when it’s pretty fresh from the oven.
