The cobbled streets surrounding 14th-century Galata Tower in the Karaköy district buzz with independent boutiques, vintage stores and trendy cafés serving cold-brew coffee and organic vegan muffins. Many visitors come over the Galata Bridge for a spot of window-shopping and return clutching bags full of designer clothes, a handmade lampshade, a hip t-shirt or a unique gift. Take time to stroll down the liveliest streets, like Serdar-ı Ekrem and Galip Dede, where you'll find countless designer clothes stores and music outlets.
