The O’Reilly 3004 introduces itself as a gin bar, making a reference to Alejandro O’Reilly, the Spanish military of Irish origin, that arrived in Cuba as the head of the Spanish troops shortly after the British occupation of the island for a while in the 18th century, and reorganized the Spanish army.

Even though, the area of the small interior is extended by the mezzanine, the tables are a little bit close to each other. The small bar on the ground floor has a few metal seats. The walls are covered with modern artworks, screen prints and photographs. The restaurant has a good air-conditioning that rescues you from the humid air of the street and a sound system that plays soft music. The crowd consists mostly of the tourists and some local affluent hipsters.
