Ubicada al primer pis del Mercat de les Flors, la sala Sebastià Gasch, amb capacitat per 80 persones, acull principalment concerts de petit format o petites representacions. Sebastià Gasch (Barcelona, 1897-1980) va ser crític d’art i un lúcid cronista de les arts de l’espectacle. La seva ploma va ajudar a posar de relleu expressions escèniques com el circ, l’il·lusionisme, el music-hall i les titelles, desterrades per l’alta cultura. Company d’estudis de Joan Miró i amic epistolar de Federico García Lorca, Gasch va ser l’impulsor del Manifest Groc, escrit que s’oposava a la cultura noucentista i que també van firmar Salvador Dalí i Lluís Montanyà. La seva ploma es va prodigar en nombroses publicacions, entre elles, la revista Destino.
