Zielony Balonik (literally, the Green Balloon) was a popular literary cabaret founded in Kraków by the local poets, writers and artists during the final years of the Partitions of Poland. The venue was a gourmet restaurant of Apolinary J. Michalik called the Michalik's Den (Jama Michalika). The cabaret was founded in 1905 and ran regularly until 1912 (staged occasionally until 1915).
