I think if you go to one of the posts above (DL Links - restaurants), that should help you get to a place that has menus.
For a toddler, I would think they like pooh and friends. They have that at Plaza Inn, which I really enjoyed when we went a couple years back. lots of interaction with the characters and good food. At Storytellers in the GC, you get chip and dale and pluto - but they don't come to the tables, just stay at the front. We've also been to Avalon Cove in DCA for dinner - character interaction there is great as well, with minnie, goofy, pluto, chip and dale. That's more of an adult place IMHO....
I'm sure others can give you some good ideas for places with kids. We don't have any unfortunately, so tend to stick with the same character meals when we go.
