The 99 Restaurant in Charlestown, the last Boston location of the chain, may close due to a proposal by developers to replace the lot around it for apartments at CharlestOWN's Bunker Hill Mall. The restaurant has been at its 31 Austin St. location for 33 years and is exploring its options to remain in the community. The property owner, New England Development, originally proposed a plan in 2021 that would build apartments around the 99 in a U-shape design, but since a key zoning change in late 2023, the Boston Planning Department changed the site's zoning from neighborhood shopping to mixed-use, paving the way for residential builds. Concerns were raised about parking and the potential loss of retail, but it is unclear which stores will stay.
