If you want to drink butterbeer, you can only go to the Harry Potter campus.

Location 1: Hogsmeade Wizarding Village

When you enter Hogsmeade Wizarding Village, you will see some barrel-shaped shops where you can buy them. You can choose Ice-cold and room-temperature butter beer costs 50 a cup. You can also buy the one that comes with a water glass. It seems to be more expensive. I forgot the specific price. Personally, I like the iced Butterbeer. It tastes pretty good, but it’s sweeter anyway, like the taste of ice cream when I was a kid.

Location 2: Three Broomsticks Restaurant

Another place is the "Three Broomsticks" restaurant, which is also in the Wizarding Village. It is a must-visit for everyone visiting the Harry Potter Park. The food in the restaurant is quite solid and not very expensive in the park. You can eat delicious pork and chicken. You can also buy butter beer at the same price.
