You can take the boat from MGM to the Boardwalk and eat at Spoodles. The same goes for the boat to YC/BC for Yacht Club Galley and Cape May Cafe. There is also Fresh at the Swan (or Dolphin?).
I would do a late breakfast at Spoodles. Tour the park for an hour or two, then hop the boat to the Boardwalk and have a nice breakfast at Spoodles. Yum!
I'd choose Starring Rolls. We usually do our EMH rides like TOT and RnR and get another FP for one before we go here to eat. They have good bagels, danish. oj, coffee etc. Seating is outside only so beware of the birds.
The ABC Commissary is open for breakfast and they've got some really healthy options as well. I like the yogurt and berry parfait myself. <--- Sorry, no dancing berries.
