A dirty, squalid place from the sale of all sorts of junk, with prices already higher than in online stores. The attitude is boorish, no one knows what and where is in this pile of garbage or pretends not to know.. You can ask the neighboring kiosks "can you tell me where the photo kiosk is?", even though it will be through the wall, no one will tell you anything. I get there once every couple of years, nothing changes, the same disappointments.
The radio station. You can purchase any gadget, as well as accessories for them. There is a repair of equipment. Everything for television, a lot of radio boards and spare parts for televisions, computers, phones, etc.
A place where you can repair your gadget at times compared to the official ones, buy cheap accessories for it; sell / buy a used device; cables, ancient chargers, etc. But get ready for the labyrinths of stalls, cramped and dirty passages.
