My twin sisters are turning 40 next month, so the rest of the family would like to send them out to dinner with their husbands. None of us are from Charlotte, so we have little clue as to where to send them. They both have young kids, so they just about never eat out. Neither of my sisters are at all adventurous when it comes to food, so my sense is that something in the American/Southern vein would be best. Ambience and service are just as important as food.
Places that seemed promising were FIG, Barrington, and Ratcliffe on the Green, but I'd love to hear any suggestions.
