The series has been adapted multiple times: as a live-action television drama that aired on Fuji TV in 2001, as a four-volume audio drama released from 2002 to 2003, and as a television anime series produced by Nippon Animation and Shirogumi that aired on Fuji TV's Noitamina programming block in 2008.

[8][19] In contrast to the main manga series, Antique Afterwards is more overtly influenced by the yaoi (male-male romance, also known as boys' love or BL) genre, and has sexually-explicit content.

This includes both sexual encounters merely alluded to in the original series and slash fiction-inspired scenarios that depict same-sex sexual encounters involving the series' canonically heterosexual characters;[20] for example, in one such story, three female customers tell each other improvised erotic stories involving Antique's staff.

[19] In 2001, the manga was adapted into the live-action television drama Antique: The Western Cake Shop (アンティーク ～西洋骨董洋菓子店～, Antîku: Seiyô Kottô Yôgashiten), which aired on Fuji TV from October 8 to December 17, 2001.

[29] In North America, the series was licensed by Nozomi Entertainment, which released Antique Bakery on DVD on April 5, 2011.

The film was directed by Min Kyu-dong and starred Ju Ji-hoon as Kim Jin-hyeok (Tachibana in the original series), Kim Jae-wook as Min Seon-woo (Ono), Yoo Ah-in as Yang Ki-beom (Kanda), and Choi Ji-ho as Nam Soo-yeong (Chikage).

[32][33] In December 2020, Thai production company GMMTV announced that it was producing a live-action television adaptation of Antique Bakery titled Baker Boys.

[34] Antique Bakery is noted as Yoshinaga's first major commercial success as a manga artist, following a career in which she was best known as an author of boys' love (BL) and dōjinshi.

[35] In his review for Anime News Network, Jason Thompson commended the series' simple art, and praised it as "one of the few bishonen manga which depicts gay characters and prejudice in even a remotely realistic way.

"[36] Cathy Yan lauded the series' voice acting in her review for Manga Bookshelf, but criticized its animation as overly reliant on CGI elements.

[43] Desserts in general are seemingly ke for being delicate and "unmanly", but their exoticism as French pastries for a Japanese clientele, as well as the level of skill and craftsmanship required to create them, renders them as hare.
