As Thai places go, Thai Chef will successfully fill the hole for Thai but not necessarily impress you. If you live in Ronco-town, delivery is a nice option because I've discovered not all delivery places will serve the area.
The specialty curries we ordered in were pretty solid, and spicy asparagus with shrimp did not disappoint. The sole time I ate in was on a very slow Tuesday night, so service was prompt and the Tom Yum soup was good.
Again, it's not going to knock your socks off but it's good Thai in an area where there aren't a lot of Asian options.
