Hi Rachel,
    Thank you for the interesting question!  
  As a Mom to two daughters about the same age as your son, I completely understand your hesitation to order two meals. So I am very happy to say that yes, you are absolutely welcome to share a delicious and exciting meal at 
Teppan Edo.  This way everyone can still enjoy the lively Teppan-yaki-stlye cooking without leaving too much of that yummy meal behind.  
  Just a thought: Since you will be exploring World Showcase, I think your son might really enjoy defeating the evil Dr. Doofenshmirtz in 
Disney Phineas and Ferb: Agent P's World Showcase Adventure! Your son can be recruited into this bold adventure in either the International Gateway or near the Italy Pavillion. He will be assigned a F.O.N.E or Field Operative Notification Equipment to help him find clues and complete his critical mission.  It really is a blast!  
  I hope this helps, Rachel!  Come back and visit us if we can answer anything else for you.  
  Wishing you many magical memories,  
  Sally
