At Universal's Islands of Adventure there is a character breakfast offered at the Confisco Grill. We've done this twice, and the characters we saw included Spiderman, Dr. Doom, Wolverine, The Cat in the Hat, the Grinch, Olive Oyl and Woody Woodpecker. I don't think it's offered every day. You might want to check their official website for details. Also, I don't think very many people are aware of this - both times we went the restaurant was far from crowded and we had plenty of time to take many pictures with the characters. The food was a buffet - nothing special.
