We went there last trip more because it is so insanely popular and gets such high praise, partially for being a 1 TS restaurant. I was pleasantly surprise how good it was! While I thought the steak I had (Kansas City Strip) was quite good but not amazing, but everything else, from appetizers, beer cheese soup, the pretzel bread, the yukon gold au gratin potatoes and desserts were all top notch! DW had the filet, and that was melt-in-your-mouth good. Some say it is overrated, but to us it was one of the best meals we've ever had at Disney, and plan on going back should we be able to get a Table. (I Loved the smores desert.)
BTW, our waitress was excellent...we had a long talk about Hockey and the winter Olymipics (she was from Vancouver). Hint with any Canadian - if you want to start a conversation, mention Hockey, they'll talk for hours.

P.S. To the PP that said they'd just as well go off-site to Longhorn...BLECH! If you are satisfied with their steak, then I wouldn't bother with Le Cellier either.
