I've tried both Wongs and I can say with certainty that I prefer Big Wong.
Since Big Wong closed, I heard that Peter Wong (her brother's place) is fairly similar but I don't think they even come close. When I arrived for dinner, I noticed the decor was very dated. They still had decoration up from the 80s. There was also a mini stage available for wedding, if anyone is interested.
There were two other parties there but no host was to be seen. It appears to me that there was only the mother/son team working the kitchen and the front of the house. So service was slow all night.
We ordered: deep-fried tofu, stuffed with shrimp; orange flavored chicken and honey walnut shrimp but I was told that they ran out of the sauce for the walnut shrimp (which was mayonnaise) so I switched that out for the roasted duck.
The deep fried tofu was missing a lot of shrimp and by a lot, I mean "stuffed" was used loosely on the menu. The roasted duck was heated up in the kitchen because there were pieces that were refrigerator cold. The orange flavored chicken was missing flavor.
Gordon Ramsey and his Kitchen Nightmare team need to visit this place. I know the owner is a nice person and her son, looks like he hates working here and probably only doing it to help his family out.
