Good friend of mine, who is a reasonably well-known food personality, will be in Dallas for 24 hours. We're taking him out to dinner, and we're in charge of picking the spot. He's really into the farm-to-table movement as well as sampling indigenous fare. I want to show him Dallas' sophisticated, urbane side. Price is not an object, he may not want to get dressed up though. This dinner is not for his job at all, but I want to make sure that one of his rare "dinners off" is a great one. Where would you take him?
