I ordered takeout from Wan Fu in October of 2016 after finding another Chinese takeout restaurant nearby closed and scrambling to find something else. Wan Fu has great reviews on Yelp so I was looking forward to some good Chinese food, which has proven difficult to find in Charlotte in my 10 years here.
My barometer for comparing Chinese takeout is tofu with vegetables in a brown sauce. It allows me to judge how well a restaurant can stir fry vegetables, which is more difficult than stir frying only chicken, such as General Tso's.
Wan Fu's tofu with mixed vegetables in brown sauce was very disappointing. The tofu was great (it's hard to mess up fried tofu), but the vegetables included yellow squash and baby carrots that were way over cooked and thus limp and mushy. The sauce was watery, as if some of the vegetables were frozen. There wasn't much taste to discern in the sauce other than bitterness.
For $11 for a basic tofu dish, Wan Fu isn't worth the visit.
