The operator of the Innovation and Design Building in South Boston is seeking approval to add a full-service restaurant and several quick-service food outlets on the ground floor of the 1.4-million-square-foot complex.

One restaurant offering seated dinner service would be located on the first or second floor of the complex, and several “grab-and-go” outlets would be located on the ground floor, according to the application filed with the Boston Redevelopment Authority.

Atlanta developer Jamestown, which leases the complex from the city, is seeking to add amenities as it recruits additional office, lab and makerspace tenants. Currently, Au Bon Pain is the complex’s only food vendor, although Jamestown added a daily rotation of food trucks last spring.

Jamestown is seeking approval for one restaurant to remain open until 11 p.m. Currently, food service is not allowed after 7 p.m. weekdays or on weekends.
