My take - after one dinner there - is that if you have never been to a 5 star restaurant before, try it - it is wonderful to be catered to that way, and the food is tasty.
That being said - no, it absolutely is not worth the money -- it is the only 5-star restaurant in Orlando, let alone on property at Disney, and that leads to very long reservation lead times. The restaurant is overrated and the food portions extremely small. It reminds me of some of the 5-star restaurants we used to eat at when I lived in New York City - you go for the atmosphere and the pampering, but expect nothing from the food.
Sadly, that should not be what going to the top-rated restaurant it town should be all about. My advise? Treat yourself to a (much better) dinner at Bistro de Paris in Epcot instead. If you are a meat and potatoes person, go to Shula's instead. You'll still spend a lot of money, but at least you will get some food on your plate.
I am also a meat and potatoes guy, and I had a hard time finding anything on the menu that I was happy with - and I agree that you need to stop and eat something on the way home -- we went over to WDW after dinner, and I kid you not I had to get a hotdog at Caseys about two hours after dinner since I was still hungry.
Is it romantic? Yes. Is it a high-quality night out? Absolutely. Is it really the best in town? No way.
