Central and the main street in Kiev. Always busy, always something happening, always crowded. All central sports events, protests, demonstrations, revolutions) happened exactly on that street. Lots of entertainment such as dancing, small music concerts, different PhotoBooth and games happening on the pedestrian part in the evening. Buildings are old, solid and Mostly historical heritage. Evening giving you a nice bright colors and some other experience. I heard, that it is widest central street among the European capitals, but not sure, need to Google it.
