Oh G-d. There isn't any really good Chinese in Orlando, but you can get some very good Vietnamese on 50 (East Colonial Drive). There is a short strip (from the I-4 exit east for a mile or so) on 50 that has several very good restaurants. There are a couple of Cuban restuarants interspersed throughout. Those serve very basic sandwiches and the like, but are quite good.
I'd check the DOH report before I ate in any of those Chinese buffet places. They are frequently written up in the paper.
