Opium Barcelona is the most iconic nightclub on the Barcelona waterfront — situated directly on Passeig Marítim de la Barceloneta with a beach terrace restaurant and a club that has become one of the city's essential nightlife destinations. Part of Grupo Costa Este (also behind Opium Madrid and Opium Marbella), it attracts an international crowd of tourists, celebrities and locals every night of the week.

The club is home to three signature weekly events: WEDJS on Wednesdays brings commercial and house DJ sets with headline international acts; WAA!! is one of the most energetic summer residencies in Barcelona; and CRIB on Sundays delivers the best in urban music, reggaeton and latin trap — having hosted artists including Tyga, De La Ghetto and DJ Diesel. The restaurant features fresh Mediterranean cuisine right on the beach, with rice dishes, meat and salads.
