CHESTNUT HILL (WPVI) --For 'Harry Potter' fans, Saturday is pretty much the Super Bowl - or you could say the "Quidditch Cup".
It's the 6th annual Harry Potter Festival in Chestnut Hill, and the largest and most exciting yet!
Whether you're a Potter die hard or new to the Hogwarts School, there's magical fun on tap.
Germantown Avenue will be magically transformed into Diagon Alley, and everything's coming up Potter.
We started at Villavillekula to, you know, look the part.
Store owner Beth Milley says, "We always have the scarf - the signature scarf. And when you buy it you get the glasses."
Up the road at Threadwell, wizards big and small can stock up on all kinds of Hogwarts essentials.
All of the businesses are all in, taking great care to channel the mystical essence of the immensely popular series, and muggles come from near and far.
Martha Sharkey, executive director of the Chestnut Hill Business District, tells us, "We have seen people come as far as Washington, families from LA, Ohio, North Carolina, Tennessee."
For the first time ever they're shutting down Germantown Avenue. And there's tons of free fun, including a session with the sorting hat.
The Chestnut Hill Hotel is now "The Rail View Hotel".
Hotel manager Lindsey Pete says, "We have brides and grooms that specifically booked the hotel this weekend because of the festival."
The next door Market at Fareway is selling all kinds of delicious 'Harry Potter' delicacies, from crunchy chocolate frogs and pretzel wands, to a bread cauldron with exploding dip from What a Crock.
And of course butter beer. And this year they're kegging it!
For libations of the alcoholic kind, Paris Bistro has a funky green potion for you.
Ginevra Reiff, beverage director at Paris Bistro, explains, "We went with polly juice potion this year, which is a drink that you drink when you want to change your identity for a short amount of time."
On Saturday, SEPTA becomes the Hogwarts local. Harry and Dumbledore will be at Jefferson Station from 9-10 a.m. and riding the train with festival goers to Chestnut Hill.
