I shop at Kam Man Market in Quincy pretty regularly, but I've never tried the "deli" there before.
I was there around lunchtime on Saturday, and decided to try it. I bought one of the whole marinated ducks for $14, along with some side dishes of spicy chicken and tofu and pork with Green Beans.
The food was just delicious. The duck was juicy and meaty. One of the best roast ducks I've had in a while. The other dishes were quite good as well. Really tasty, with a nice kick from the chili oil, and big tender pieces of chicken. Not overly greasy, either.
The "small" bowls were $5.95 each, and easily enough to share. They have a pretty big selection of prepared foods, and it all looked wonderful. Definitely something to consider for the next time you are in the area and looking for Chinese take out.
