Why locals love it
A bookstore familiar to every Muscovite, located in the city centre (near Lubyanka). There is wide choice of books (in the first floor - also in English and other languages).
It's also a nice place to buy souvenirs (you can find them in the ground floor).
Why you should visit it
You can get souvenirs or books in Russian (why not?)
And it's just a good place for lovers of bookstores (like me!)
P.S.There might be queues (not very long, 3-4 people in a row) in the evening.
