It's sharable...with ants. One adult, dining alone, will go looking for a hot dog.
Yorkshire has to be the worst use of a CS credit at WDW! It is a very small portion of okay food served by some of the nicest CMs at WDW. I love Fish 'n Chips, but this is just far too little food for even a light lunch.
Skip Yorkshire, use a snack credit for popcorn, and you'll be WAY ahead.
