It's russian word which means "Happiness". That's very beautiful place with amazing view at summer time cuz they have an open terrace and u can enjoy pure sunlight. Menu of breakfast is really nice and everybody will find something for every preferences. Eggs, pancakes, porridge, granola… whatever! That's my favourite place in Moscow =) And also u can buy sweet gifts for your friends cuz they have outstanding candy's brand shop at the entrance:)
