Hafiz Mustafa has been in business since 1864, selling a huge variety of Turkish Delight and Turkish pastries. Their flagship store is on the street corner near the port and train station in Istanbul, at Hamidiye Caddesi No:84-86. You'll often see people lining up for the sweets at Hafiz Mustafa.
The sheer number of sweets and pastries produced by Hafiz Mustafa is almost unimaginable. If you have a sweet tooth, you'd do well to go to the website before your vacation to get the juices flowing and to see the variations on something as simple as Turkish Baclava. Here's an interactive page on the products. Even if you're not going on vacation to Istanbul soon, you'll get an education on how Turks transform sugar into an enormous variety of edibles.
