THAT'S what makes the DIS so great. You get lots of opinions.
For me, I hated my Concourse experience. Loud, rushed, close quarters, no "extra" attention at all. Le Cellier was relaxed, quiet, seated in about the same amount of time and the rissotto was fabulous. (pretzel bread doesn't do it for me, but the whole grain....)
You can listen to the "reviews", but you really need to make up your own mind. Check the menus, any one restaurant might/might not be right for your family. And don't forget, the experience that any one family has is going to be different from another....even if they were visiting at the same time!
