We went to the character bfast and had a great time. As others have mentioned, the food doesn't appeal greatly to adult tastes, but my kids loved it. That's rare!
Spiderman was AMAZING. He really knew the character inside and out. He moved like a spider, he was strong enough to lift my boys up intheir chairs for pictures, knew movie and comic book trivia like he had really lived it, and had great conversation skills. My six-year-old LOVED it! My two-year-old thought he was pretty cool too, and kept shouting, "Man! Man! Man!"
Thing 1 & 2 were also there, and Cat in the Hat. They were funny and really knew how to interact with my kids. We got some great video and pictures. It was well worth the time, and the kids ate well enough to give them a good start for the day.
