Here’s a true oasis: an elegant classical-music lounge-bar in the midst of grungy Camden. And not only is it an original find in this area, it’s pretty unusual in the whole of London. Named after the Hungarian composer and pianist, Bartok specialises in classical concertos, live jazz or brilliant DJ sets blending jazz, classical, electro and world music. Sadly the beer choices are standard issue, though cocktails are good here – kick back on one of the low sofas and enjoy until the wee hours.
