I've eaten at the food bar a few times, but only when I've been having the special chef's tasting menu. This is a five or six course extravaganza where a personal chef cooks right in front of you and whoever else has opted for the tasting menu (10 person max).
It's a great experience, since you get to kibitz with the chef and ask all sorts of questions and get to see the kitchen in operation, which if you're into that sort of thing is a lot of fun.
However, if you were not taking part in the tasting menu, I'd think you'd feel kind of left out. Also,the way it's set up, you can't really soak in the atmosphere of the rest of the restaurant unless you completely turn around.
Of course, maybe they won't be doing the chef's tasting menu thne night you'll be there, which is why they put you there. Or here's a really terrible thought -- they've discontinued the tasting menu!!! I hope not.
