Yup - I think it is most definitely worth it, especially since it's something you're not likely to experience otherwise. We've taken first-timers there and they've loved it, and I've recommended it to friends who have loved it as well.
The food is great, but also light and relatively healthy (that's something to be said for WDW food), and we've always had great service - especially on our drinks ... beer and wine barely gets past the glass half-empty stage before they bring you another one.
I wholeheartedly recommend it!
