Is a different kind of mall to visit
Also is really expensive to buy clothes or anything here, but if you visit Moscow you have to go to the Gum, and also to go to the bathrooms, they are payed in the first floor, and free in the third one, but you have to see yourself the ones that are payed, the cost if I remember it well is of about ₽130-₽200 (I went long time ago, so I don't have this information fresh)
