Our dinner there last month was the best we had in WDW the whole vacation. However, since I tend to find WDW food to be very ordinary (like the chain places at home, more or less) and I have not done any "2 credit" restaurants, it is probably not the most delicious meal ever, just very good in comparison.
I have been to very good steakhouses at home which are comperable both in price and quality of food. The service we had at Le Cellier was outstanding, though.
