Where to get a good cup of coffee in Belgrade

Coffee shops have always played a significant role in the social lives of many people. It's where we meet up with friends, get some work done on our laptops, do a bit of writing or reading, or simply observe the world around us. There's a special kind of relaxation that comes with a good cup of coffee and the ambiance of a coffee shop. As someone who's often first in line when a new coffee shop opens, I'd like to share some of my favorite spots in Belgrade with you.
