I don't have just one favorite; I love 'em all!
I guess if I were to put everything I've ever tried in the order of preference, it'd be: Greek, Italian, Peruvian, Thai, Eritrean/Ethiopean, Indian, Vietnamese, Chinese, Korean, Japanese, Mexican, American (i.e. burgers, diner-style food, etc), and French.
There's a Polish place that I've been meaning to try. I'll report back once I do.
