We have only ever ordered this for take-out, and overall it's pretty good. The part I absolutely love is the fact that you can order online. They have always got our order correct, despite the fact that I always fill up with "Notes" section with my extra requests. The delivery people have been friendly and quick.
As far as the food, it is definitely not my favorite Chinese ever, however, the flavors are decent and they give you a pretty fair portion. We always go with the General Tso's chicken, Lo Mein, and Dumplings. Go with fried dumplings, as opposed to the steamed (they're always kind of flimsy). Lo Mein is normally pretty good. The ease of online ordering and the fact that overall it's been good is what keeps us still eating Hot Wok.
