The Blue Lassi shop is one of the highest rated restaurants on Tripadvisor for this area and has been open for 70 years. Lassi’s are really common yogurt snacks thought India and Nepal. The restaurant, like most, is basically a concrete box on an alley in a marketplace. The kitchen consists of a guy sitting on the floor mixing yogurt with different fruits and spices. I got a saffron and cashew mix and it was pretty amazing.
