Unfortunately they chose to close the one I thought had the best theming, and that was Ariels at the Beach Club... it had this whole "under the sea" motif going on. It is now used for private functions.
That being said, I would say my favorite restaurant as far as theming would be a tie between 'Ohana and Artist's Point.
Eeyore, glad somoene else remebers Ariel's . I wish they'd open it to the public again, I feel there is a need for a good seafood restaurant on property. Can't believe they closed it.
