Why is that? I don't care for the decor of leCellier but the steaks have always been melt in your mouth, tender and juicy. Unless major improvements have been made I don't understand the signature status change but the food there is good. What do you consider to be a steakhouse?
Honestly, I don't feel any WDW restaurant is up to par with whats available offsite for the money. You're paying for the unique qualities of most of the restaurants at Disney as well as convenience. I haven't found any bad restaurants at WDW but some are certainly better than others.
