The Pirates buffet starts right after the fireworks which usually go off at 10:25 p.m. They start setting up quite a bit before that, though.
They have turkey legs, fajita bar, warm crepes with ice cream, and several other things on the "hot" side, and loads of desserts on the other. On our next cruise, I'm saving up for fajitas that looked scrumptious and the warm crepes that are delicious.
