A real Cantonese restaurant, replete with hanging ducks in the window and everything. Get the crispy pork, and also some variant of the noodles. I love the tofu as well. I am less enamored of the duck and chicken, but this is an excellent restaurant, and very authentic, in the hands of a wise orderer. It's also very cheap, so take advantage of the prices to order many items. Great dim sum too.
