Shopping and training center.
The basement and the first floor are basically everything for mobile devices, accessories, cases, craftsmen, accessories and of course new and used phones.
Second and third floor: beauty salons, cosmetology, ateliers, toys, educational centers (foreign languages, exact sciences, etc.)
I remember a long time ago there was a dining room in this building, a good one was visited after everything was reorganized these days there are small boutiques here, mostly mobile phones, spare parts for mobile phones, so far all I can write
