ABP OPCO, LLC, doing business as Au Bon Pain, (French pronunciation: [o bɔ̃ pɛ̃], meaning "at the good bread"[2]) is an American fast casual restaurant, bakery, and café chain headquartered in Richardson, Texas, which operates 175 locations in the United States, Thailand, and Taiwan.

[5] Pavailler,[6] a French manufacturer of baking equipment, established the company as a showcase for its ovens in 1976 at Faneuil Hall in Boston.

[3] Francois Marin was hired to open and manage the first Au Bon Pain in Boston's Quincy Market.

[19] In 2000, the company reached a franchise agreement with Gourmet Coffee Co. Ltd. of Taiwan to open the first locations of Au Bon Pain in Taipei.

[21] In 2005, Au Bon Pain management, in partnership with PNC Financial Services, purchased 75% of the company; Compass Group retained the remaining 25%.

[33] In December 2019, Au Bon Pain closed its last remaining Cambridge, Massachusetts store, ending over 35 years of business in their former flagship city.

AMPEX Brands declined to disclose the exact value of the deal but confirmed the inclusion of assets and franchise rights for 131 additional locations.

[37][38] Decreased urban foot traffic caused by the COVID-19 pandemic resulted in more closures, leaving only 123 stores in the United States.
