"Overall, I thought the user experience was good. If this is on an airplane, it should be on a default screen as opposed to being bombarded with the words "Eat" and "Drink" when you chillin." Maybe even instead of "Eat" it could be "Food"."
"Instead of taking away what you don't want for the sandwich or other items, you could add what you do want."
"There should be a button on the screen that can take you to any of the other menus without having to go back to the main food menu. Maybe that could be done through suggestions when you select a food like, 'Hey, did you want to add desert to that order?'"
