In 1899, at age 17, Picasso started to frequent the place and carried out his first exhibition in the big room. Also he made the poster that was used as a title page of the menu of the house. Musicians like Isaac Albániz and his friends Enric Granados and Lluís Millet also visited the 4 Gats, as well as architects like Gaudí and draughtsmen like Ricard Opisso. The streets of Barcelona came off impregnated with the Bohemia that they left and the aroma of those that changed impressions about the future of their time can still be breathed today. Those first years, the most luminous and expressive, have come off retained on the tables and are now hanged on the walls. They are all there: Picasso, Casas, Opisso, Nonell, Rusiñol; they certify what happened during those years in which the artistic feeling of Barcelona and that of a place full of inspiration vibrated.
