He would probably love the Sci-Fi Drive in - you sit in cars at a pretend drive in to eat. I know this is the one my 11 yr old daughter is looking forward to most.
Also, if he is an outgoing kid, the 50s Prime Time Cafe is fun. Also Whispering Canyon is fun.
Chef Mickeys is a great character dinner and really fun. Crystal Palace is nice and Liberty Tree Tavern is nice too.
