I think that's supposed to be Vidalia's niche except: 1) they are pushing the upper end of your price point; and 2) personally I've never felt it lived up to the price/hype. The few times I've been I was underwhelmed.
Second Creme; it's closer to the bottom of that range, cute space, fun atmosphere. My companion claimed the shrimps/grits/smoked sausage were beyond words; even the vegetarian plate o' the day was pretty darn good. Riffs on southern food without being ridiculous.
