There are so many restaurants in Ann Arbor. One opens everyday or so.
Still, for years, one of my favorite for casual very good American cuisine, RH is my fav'. and the staff is as cool as efficient. Gumbo? I love it before a beautiful RH salad or a lamb burger (when I was not a vegetarian).
To me it's the best marinated tofu in Ann Arbor (OK I don't know all of them but still!
I'm at home there.
