Although Melissa McCarthy is working hard these days on the Boston set of Ghostbusters, she knows how to have a good time.

On Sunday evening, McCarthy, 44, and her husband Ben Falcone, 41, headed to Boston’s Italian North End, where they grabbed dinner at Mare Oyster Bar. Dressed casually, the pair shared oysters on the half shell for an appetizer.

For their main course, the couple enjoyed pan-seared salmon with white bean puree, roasted fennel and shallots with bagna cauda sauce, as well as pan-roasted halibut with corn and clam chowder, saffron, littlenecks and grand andouille sausage.

“She was super nice to the staff and to the other guests at the restaurant,” an onlooker told PEOPLE. “On her way out, she said ‘hi’ to guests who went up to her, and also thanked the staff for everything. She said she loved it.”

While it was just the two of them on Sunday, McCarthy and Falcone hit the town with another couple earlier in the week. On Monday evening, the duo met up with Ghostbusters director Paul Feig and his wife, Laurie Karon Feig. The foursome were spotted having dinner at the Butcher Shop in Boston’s trendy South End neighborhood. The French-Italian wine bar and butchery is owned by Chef Barbara Lynch, who is a friend of Feig.

McCarthy officially began working on Ghostbusters this week alongside stars Kristen Wiig and Kate McKinnon. The ladies were spotted on Thursday filming at the former Everett High School in Everett, Massachusetts. Made over to look like the Bronx Kuyper Middle School, the building had large banners draped across the front reading “Higgins Science Institute.” Multiple New York City cabs lined the road in front of the school.

McCarthy has been vocal about her love for the Bay State ever since she spent time in Boston shooting the film The Heat with Sandra Bullock a few years back.
