ET stares at you through watery eyes, Spain's answer to the spandex-clad Jane Fonda of aerobics, Eva Nasarre, is a bit spunkier, Cyndi Lauper is caught in a moment of paint-swatch joy, and from the sound system blasts a big-hair ballad. This is the kind of place that makes you remember why you took up karate, hoping for a sensei like Mr Miyagi, it make you sure you can solve that Rubik's Cube if you only had another shot, it makes you want to see 'Back to the Future' again, for the first time.
Yes, the Polaroid Bar is a shrine to the 1980s, paying tribute to those snapshots with the little white frame. Vinyl, VHS tapes and those famous cameras cover the dimly lit walls. The bar area boasts all the colour, with fluorescent lamps that absorb all the nostalgia and use it to make pendants. The crowd rushes in early, to get the night started, and to take advantage of the 1980s-priced beer, at just a euro for a glass. And of course the cocktails bear names like Miyagi, Delorean and Sarah Connor.
