This place is great. Most dishes are authentic Chinese except for a few, which are Americanized. My favorites includes Ma Po Tofu, Salt and Pepper Pork Chops, Roasted Duck, Pan Fried Cantonese Style noodles, and Lo Mein. However I wouldn't recommend the Walnut Shrimp (mayo overload) and BBQ Pork (not prepared the authentic way). If you want authentic BBQ Pork, I suggest going to Mekong Palace and ordering from there. The taste/flavor is completely different from what Wei Wok serves and it's more authentic/close to the real thing.
Other than that, this place is great. It definitely puts Panda Express on watch since it's just a few blocks down the same street!
