Would cruisemates like specialty food carts in designated areas at specified times. Some food carts could be associated with restaurants on the ship. A Johnny Rocket hamburger cart by the swimming pools. The food served from the cart could be specialty type. The vendor crewmember would then prepare and serve the specialty food from the cart.
Each cart would have a food specialty like Indian Kaati rolls and biriyani, Salvadoran pupusas and tamales, Korean tacos,.
Greek foods, especially souvlaki, gyros, pita such as tyropita and spanakopita (respectively, cheese and spinach pie), Belgian-style fries, waffles and poutine
The cart idea could be extended to specialty wines, beer and liquor. Specialty carts could be used for a food festival or to celebrate a food holiday like National Doughnut Day and the carts could be put on the pier to serve passengers they leave and board the ship.
