Let me give a few of my favorites when I visit my brother.
Birmingham: G, in downtown area. Try the green tomato soup. (It's also an Idine eatery.)
Bottega is a great Italian place. It's in a converted bank. One side is more sports bar, the other fine dining.
Huntsville: Jazz Factory, on the square. Hands down one of the best places I've ever eaten. It's billed as San Francisco style cuisine. The head chef is from Alexandria, Egypt and combines some great flavors.
Tokyo, for sushi. Chef Leo is great.
