The problem with ethnic is - who determines what is "good"? I am very critical of some mexican food because I grew up with it. But when eating other ethnic foods all I know is that one restaurant's food tastes better than the other, what ever the cuisine. As far as food making me sick that could potentially occur at any restaurant at any time and may not be related to the actual cuisine but sanitary conditions or tainted ingredients beyond control of said business (such as recent problems with romaine lettuce).
As an example, I really like the Kung pao chicken at a local Chinese chain, but not so much at our favorite family owned Chinese restaurant which makes other entrees much better.
I love General Tso's chicken but it is different (sometimes very different) wherever you go.
