Katy Perry spent her weekend in Boston hanging out just like a local.

On Sunday afternoon, Perry stopped by Dunkin’ Donuts in the suburb of Stoneham, Massachusetts, where she and her entourage feasted on coffee, sandwiches, munchkins, and donuts.

Dressed in a black-and-white plaid skirt and black crop top, Perry sipped a medium hot coffee and snapped photos with fellow caffeine lovers in front of Dunkin’, even posting her own picture of her crew in front of the store. She made sure to bring another famous Bostonian: The Office star B.J. Novak, who was by her side in a Red Sox hat.

“She was very nice, very friendly,” a Dunkin’ employee tells PEOPLE. “She was smiling.”

After getting their caffeine fix, Perry and her entourage hit up the Salem Witch Museum in historic Salem, Massachusetts. They visited Crow Haven Corner, Salem’s oldest witch shop, and participated in the Salem Witch Walk. According to the tour’s Facebook page, Perry did join in on performing a witchcraft ritual, but it was strictly “love magic.”

“Which witch is which?” she captioned an Instagram at the museum.

Perry also headed to Harvard University, where she visited The Harvard Lampoon, the school s humor publication. She was spotted taking pictures outside the Lampoon castle in Cambridge.

The “Roar” singer was in town to perform Saturday night at the TD Garden. On Friday evening, she and Novak headed out for drinks at Saloon in the trendy Somerville neighborhood.
