Visit the Grand Bazaar or The Spice Market
The Grand Bazaar is a great place to stroll around and get the feel of what it is like to be in a middle-eastern spice market. It is one of the largest covered markets in the world covering 61 streets and has over 4000 shops inside. It is a sprawling network of crisscrossing streets full of people and shops selling all kinds of goods like trinkets, jewelry, gifts, and souvenirs along both sides of the streets.
Once you are inside, all of your senses will be engaged from all directions with the sound of the people, the smell of spices, and the colorful visual of all the people and shops along the streets. If you are looking for something closer to the Old Town, the Spice Market is also highly recommended. The Spice Market and its surrounding areas will give you a similar experience to the Grand Bazaar but without you having to go very far from the Old Town area.
