A group of us had a chance to check out The Wizarding World of Harry Potter before it's official open. We arrived in the early evening and spent a couple hours experiencing Hogsmeade and drinking butter beers.
The main area is Hogsmeade. There are a few places where you can try some of the foods from the magical world of Harry Potter. Butter Bear was interesting but way too sweet for my taste.
This is the view of Hogwarts castle when you are walking around Hogsmeade.
