History and specifics
In the year 2370, Keiko O'Brien offered zabo stew for dinner to a guest, Rugal. Both Rugal and Keiko's husband, Miles O'Brien, disliked the stew. (DS9 episode: "Cardassians", ST reference: The Star Trek Encyclopedia)
In the early 25th century, Cardassian zabu stew was commonly available from replicators on space stations and starships. It was also sold at various bars for a price of 20 energy credits. Such vendors included Club 47 on deck 47 of Earth Spacedock, Quark's bar on DS9's promenade, the 602 Club at Starfleet Academy on Earth, and Andorian park rangers on Andoria.
In the Alpha Quadrant, zabu stew was used by Khitomer Alliance duty officers to fulfill assignments in the Kalandra sector. (STO - Cardassian Front mission: "Heading into Deep Space", duty officer assignments: "Prepare Kalandra Sector Surprise", "Develop Variations of the Kalandra Sector Surprise")
