If it’s not summer and you’re in town on an evening searching for a little subterranean excitement, try Nu Club, one of the most fashionable clubs in Istanbul. It is part of the Nu Pera building, which houses Lokanta, the excellent fusion restaurant on the ground floor (see Eat), and Nu Terras (see Snack), its summery incarnation on the seventh floor. rnrnNu Club is small, loud and often densely packed with Lokanta/Nu Terras’s smart, attractive clientele who generally range from their late 20s to their early 40s. The intimacy is all part of the attraction, especially on the dance-floor, which, though modestly proportioned is often lively. rnrnThe DJs tend to put out a mixture of house and more dancey pop hits, and there’s a strong Parisian connection thanks to some of the promoters, who regularly lure Gallic trendies over to take command of the decks for a bit.
