Meals once an hour, from the time you get there (though pre-11:30 am it's only continental breakfast) until 1/2 hour before it closes. You can choose to get the entire meal, or a snack (fruit, cake, jello, pudding...) or both. You can get drinks as many times as you want in a day, but you can only get it through the quick service restaurants, not the drink kiosks.
