Food and drinks are available at several places in the park. Primarily, the Three Broomsticks, the Hogs Head, and the Butterbeer cart offer food to be eaten. Candy is also available at Honeydukes.
The Three Broomsticks offers Breakfast and Lunch/Dinner. Breakfast is standard breakfast, mostly including eggs, pancakes, and sausages. Lunch offers several options, including a "Hogwarts Feast" (something that resembles a thanksgiving feast) for a family of 4, and some british themed food, like Fish and Chips.
The primary attraction in this category is the Butterbeer - available at all three food locations. There are two versions - frozen and regular. Both versions are topped with a magical foam that grows slightly after it has been dispensed. Most reports say that the frozen version tastes a little less sweet than the regular. Butterbeer tastes like Cream Soda, butterscotch, sugar, and Christmas in a cup. The park claims that the recipe for Butterbeer was approved by Jo Rowling.
Pumpkin Juice is also a beverage that can be bought 'on tap' or by the bottle. The bottles are topped with a plastic pumpkin souvenier. It contains apple juice, pumpkin puree, apricot puree, and a spice blend resembling those spices often found in pumpkin pie.
The Hog's Head Brew is a beer manufactured for the park. It is said to taste a little nutty.
