Faneuil Hall and Quincy Market run as a year-round open marketplace with street performers throughout the day, food stalls in the colonnade, and rotating events on the cobblestones. Free to wander; fills with crowds on weekend afternoons. T to Government Center or State Street. The plaza is private but publicly accessible — Massachusetts cannabis law prohibits consumption in public spaces, so 21+ visitors should keep any consumption off-site and bring only sealed product.
