There are plenty of Chinese restaurants in Chinatown. There are plenty of "Wong"'s too; Big Wong, Hoy Wong, Wong Kee, etc. I stopped by New Wong Restaurant two weeks ago and had a delicious lunch. I literally stumbled upon this place with my Chinatown Adventurer dining companion. If you try to Google the place, it's nowhere to be found. I was able to check in on Foursquare though.
Roast duck is tasty and fine. A satisfying bird. Cuttlefish is a dandy appetizer, that has a unique texture, but a pleasant dish.
Another good bang for your buck awaits.
