It's like your typical picnic BBQ, burgers, hot dogs, potato and pasta salads, fries, cookies, cakes served buffet style. If you want soda to drink, be sure to bring your soda card (just like on the ship). They have tea, punch and other drinks that are free.
They have lots of picnic tables set up in various places, it was nice to be able to have lunch without having to go back onto the ship for lunch. We've been there twice, it's one of our favorite stops! Enjoy ;)
