Rio de Janeiro is, in some ways, a vertical city, and you will find many shopping areas that go up…read moreas opposed to outward -- Edificio Avenida Central is one of them. Not simply that, it's also your go-to spot if you need to find anything for electronics. You have the main floors with handfuls of normal stores, but there is one particular corner of the building where you enter, and it's a multitude of stalls and kiosks for a good 3 floors, with any range of whatever you need: screen repairs, cables, phone cases, new merchandise...I first got to know it when I was looking to get my iPod screen fixed, but now place it in my mental filing cabinet for anything I need. If you're getting something repaired and have some time to kill, head downstairs and grab a burger or a beer at any of the variety of other businesses that occupy the building aside from electronics stores. Right next to Carioca metro/subway station, you can't miss it!
