I think it is a wonderful restaurant for everyone, including picky eaters and children under 3. We had both in our party last March. It was possible for the picky eaters to eat only rice, or meat, or vegetables. It was all cooked separately. The show was entertaining for everyone. When asked to name their favorite restaurant of the trip, all three kids said Teppan Edo. We are returning again in just a few weeks.
If you've ever eaten at a Japanese restaurant - it's the same experience, just in Epcot. The food tasted basically the same as our local Japanese restaurant - chicken, steak, shrimp, scallops, vegetables, rice.
It was really good and lots of fun - one of our favorites.
My family are all very picky eater's. I am more adventurous and made them try this last year. All of them requested that we go back this year..lol. Me? I would probably try something else. The food was good however and the show entertained even my littlest(2 yo) so all in all it was a great family restaurant.
