Cevahir was once the biggest mall in Europe and still feels it: six levels, three hundred and forty shops, and a glass roof with an enormous clock face set into it. It opened in Sisli in 2005.
This is everyday shopping rather than luxury — familiar high-street labels, electronics, a cinema and one of the larger food courts in the city. If you are after designer names, Nisantasi is closer and better suited.
Open daily 10:00 to 22:00, directly above the Sisli-Mecidiyekoy metro stop.
From Romance Istanbul Hotel take the tram to Kabatas, then the M2 metro; allow about forty minutes.
