Le Cellier is my favorite in WDW. But, the Yacthman's Steakhouse was pretty good also. If you're up for trying something a little more pricey, you could go to the California Grille which is at the Contemporary resort. On top of steak, they have great pork tenderloin and other selections, plus a great view of the MK! Other places you could look into would be The Brown Derby at the Disney Studios and Le Chefs de France in Epcot. I've only had one bad steak at WDW and that was at Shula's (ironically the place that's supposed to have the best steak in WDW) - but I think it was just one bad steak out of 100, if you know what I mean. That's really expensive though (and they don't have A1 steaksauce, if that matters to your daughter). Any way you go, I'm sure you'll enjoy the steak you get. Good luck!
