Concierge.com's insider take:
Less Ali Baba and more Ab Fab, this high-end neighborhood is among Istanbul's most exclusive. It's home to the expected gamut of designer stores (Vuitton, Gucci, Armani), top-dollar Turkish department stores Vakko and Beymen, the latter with its sidekick brasserie, and a host of coiffured, manicured ladies who lunch. Looking for something more homegrown? Try local names in affordable fashion, such as Yargıcı and Mudo.
