I love Walt's. The food was great, the service was excellent, I love the artwork and the views! Last time we got a great window seat and got to watch the Main Street Electrical Parade while we ate dessert -- what a treat! I love Blue Bayoo too, though.
While we're there the first week of June, we're going to Walt's for a breakfast, and our dinners will be at Annette's diner, Inventions (we hope -- have to see if we got the reservation when we get there because Disneyland Hotel guests have first rights), and Hunter's Grille at Sequoia Lodge.
If someone had a bad experience at any of these, I'd love to hear it! Still time to change our minds!
As for a least favorite -- I hated the Rainforest Cafe. While the atmosphere is cool, I thought the food was terrible, the service was only so-so. I like the ones in the U.S. much better.
