Citrico's, IMHO, is the best restaurant on Disney property (excluding Victoria & Albert's). We will be there this Sunday night - we will be at Jiko tomorrow night and Le Chef;s De France on Saturday night. I would also highly recommend Victoria & Albert's. We've been twice and, to use a word that is already overused, it is phenomenal.
I, too, would also recommend Artist Point. You may also want to try Wolfgang Puck's Upstairs Dining Room at DTD. We really enjoyed it there. Try the cantaloupe martini.
