Ask for assistance I believe they do but don't think it's main entrance
I'm sure that reception will be able to accommodate. There are several levels for dining as well as the outside. There are separate entrances to allow wait staff convenient access in and out. Don't give up on finding a way in. Go early so you aren't waiting in line and can find a parking spot. You won't be disappointed; I promise. I will be watching to make sure that I know where the accessable entrance is located for future reference.
Not sure about other entrances but the one we came in was about 4 or more steps. Also after we entered there was more sets of steps to get to the seating area they took us to. We did walk through several different seating areas & I believe there was outside seating as well that was at street level.
