There are several clubs on the Bosphorus coastline that attract the city's young wealthy crowd, differing mostly by the varying degrees of bling. Open since 2001, Angelique is one of the better ones, with renowned DJs playing mainstream beats to the well-dressed crowds. Spread over three floors of a Bosphorus-facing mansion, each floor plays a different style of music, meaning that you can pick between '90s pop or house (with a few genres in between). It's usually wisest to follow the crowd and check out which one the locals are flocking to that evening.
This Ottoman mansion has been reimagined by th cool designers, Autoban, who transformed the space into a sleek, modern layout with marble tabletops and white leather seating. This is a place to see and be seen, so you're likely to be mixing with high society and local celebrities. It also serves food (reservations recommended), with a menu that traverses the world, and features everything from duck confit to sushi. Whether or not extravagant is your thing, partying with a trans-continental view is a pretty memorable experience. There's no cover charge, but you need to be looking as fancy as the rest of Istanbul's 'it crowd' if you want to get in.
