I can only speak to the delivery services from Kwan's as I have not physically stepped into the restaurant..
My thoughts are, "meh." Maybe would taste better if I was a few beers in. I ordered lemon chicken and it was deep fried. The breading was too thick for the piece of chicken. The lemon sauce came separate in a huge plastic tub. I also ordered some other things but they were not memorable. Delivery was quick.
