In the general vicinity of the Hub area is the Plaza Restaurant (Table Service) at the end of Main Street on the right, Caseys Corner (Counter Service hot dogs and french fries) at the end of Main Street on the left, and Cosmic Rays Starlight Cafe' (Counter Service, pretty much anything you can think of including chicken, burgers, fries, salads) in Tomorrowland just over the bridge from the hub, on your right.
Since you want to see Wishes from the bridge to Tomorrowland so you can see Tink fly over, and you are looking for Counter Service, I would say that Cosmic Rays Starlight Cafe' is going to be a perfect fit.
