The name says Peking Duck house, but at Sang Kee's, all the roast meats - from Duck, Chicken, and especially Pork - are pretty good. This is very much a low frills, chinatown operation, which means reasonably indifferent service, no concept of dish timing, but pretty low prices.
It's pretty easy for non-Chinese to order and eat here, because all the menu items are quite self explanatory and there isn't any seperate 'chinese' menu like some places have.
They also offer takeout, and they sell their roast meats for take-home by the pound.
I advise coming here with a small group, as that allows you to order several different dishes and share them with rice.
