We've not eaten at all of them (in fact, maybe not even half). Of the ones we've dined at, the ones we keep going back to almost every trip are:
LeCellier
Boma (breakfast only)
Plaza Restaurant
Crystal Palace (breakfast only)
Yak & Yeti
Fulton's (not on dining plan)
I think we all understand now why it is so hard to get a reservation for 'Ohana...even 180 days ahead of time!
I guess Fulton's is on the dining plan now (signature). I was looking up all the restaurants on the dining plan and Fulton's is on there. I don't do deluxe so I wouldn't use the dining plan there but I found that interesting.
