I'd take Teppan Edo everytime. We don't eat at this type of restaurant at home so when our DS(8 at the time) sat down with us, he was thoroughly impressed. He enjoyed the entertainment while the cooking was going on. (Mickey design on the grill with the oil, onion choo choo steam, tossing of shrimp tails into his hat, etc...) Of course when we left he said, why don't we have one of these in our kitchen and you cook like that, LOL!!!!
With this being said, our son never wanted to do a character meal even when he was little so if your 10yr old really wants a character meal, I'd do that or maybe both if it fits your plan. Teppan Edo has very good food, top 5 non signatures for us. Garden grill is good too.
