This megastore is not too far from where I live, and they have a food court. We stopped in a few days ago on a weekday--it was almost empty and freezing cold. They have several counters where you can get sushi, Taiwan specialties (with an English menu that is a very rough translation of the Chinese)--mostly noodles and soup, steam-table stir fry served with rice (three dishes plus rice for $3.75), and barbeque duck and pork. There is a bakery counter too. They also do dim sum dumplings--we had the scallion and the minced pork w/vegetables--both were excellent. These are not dainty thin-skinned wonton-style dumplings--they are thick sink-your-teeth into the dough style buns that are very satisfying. As we were leaving, one of the servers offered me a taste of the rice porridge, which was sensational--a thick and flavorful congee filled with mushrooms and other things--cooked so that the rice that it was composed of had broken down and lost its shape, becoming totally integrated into the liquid base.
We have had the barbeque in the past and it is very good also.
The store itself is huge--they sell all sorts of Asian food products, plus kitchen equipment and giftware. Lots of different types of teas. Don't much like the look of the fish, though, and the produce is just OK--not real fresh and missing things (we couln't get a broccoli there).
Location--Park Avenue just south of Oak Tree Road in South Plainfield.
