The main sit down restaurant in Hogsmeade (Islands of Adventure side of Harry Potter world) is the Three Broomsticks. Like the Leaky Culdron this restaurant offers traditional English food for breakfast, lunch and dinner.
They offer a grand feast meal for $69.99 this comes with servings for 4 of a garden salad, rotisserie chicken, spareribs, corn on the cob and roasted veggies.
I went with the beef pasties with a garden salad, this salad was not as good as the Leaky Cauldron. The other adult in our group went with the rotisserie smoked chicken platter which came with corn on the cob and potatoes.
If you are looking for a lighter option, they have soup and salad option. I choose the potato leek soup but you also have the choice of split pea and ham.
Two of my girls went with mac and cheese, no surprise here. You have a choice of fries or grapes and apple sauce.
One of the girls tried the kids chicken tenders and fries. Our chicken came out a little over cooked, but the rest of our food was fine.
Out back you will find more seating with a view of the Hogwarts castle. The food here was ok. If you were only going to choose one of the Harry Potter sit down restaurants we would prefer the Leaky Cauldron in Diagon Alley.
