This two-level warehouse space just behind the Bastille is host to an amalgamation of tech-media. You can sip a cocktail to urban jazz, nod intellectually to neo-folk, be entranced by video-art projections accompanied by electro-soundscapes, or simply have a fit on the dance-floor to pumping techno. It just depends on what night you go on. Orange and blue water-filled lamps hang over the concrete bar, which is tended by a friendly, laid-back staff. Red stage lights illuminate the bare brick walls and the cocktail-list blackboards. White blinds come down over the large industrial windows and double up as screens for the well-crafted club visuals. In the early evening L’Opa is more of a bar, when trendy 20-somethings come to sit at the shiny copper octagonal tables, but slips into club mould as an (ever so slightly) older crowd joins the dance-floor. Upstairs is a further bar, decked out in bathroom tiles, with more space and tables where the partied-out 30-somethings can watch their young friends party on down below.
