I am planning a special birthday dinner for an octogenarian who loves French cuisine. There will be eight diners. The fantasy: La Grenouille. The reality: I need to keep the check under a thousand dollars. We are light drinkers – maybe one or two bottles of wine for the meal. Two of our diners are teenage boys and the cuisine of a Grenouille or a Per Se would be a waste on them (another reason why La G wouldn’t work. If we could find a restaurant where the chef could prepare a simple grilled fish or steak for them, that much better.) Someplace quiet, elegant, memorable. Any suggests are greatly appreciated. This one's a toughie, no?
