If you're unaware of what a babka is, let me break it down for you. It's essentially chocolate, hazelnut and bread BAKED INTO PERFECTION.
They are sold by the loaf at bakeries around the city, but the best I've had so far is the one they have at Breads Bakery. And they're aware they have the best one.
They bake about a million a day since they're so popular - you HAVE to try one. And I don't care what anyone says, the chocolate is eons better than the cinnamon.
