Kurazh Bazar is a fantastic monthly weekend flea market on Kyiv's left (east) bank. You'll find some 400 vendors selling all manner of new and used clothes, antiques and bric-a-brac, in addition to plenty of street food, street performers, kids' activities and live music on a large central stage. The venue, Art-Zavod Platforma (http://artzavodplatforma.com/en), is an attraction in its own right.
Occupying a gigantic former silk factory, it's a multi-use creative zone with galleries, music and fashion studios, co-working spaces and cafes. It hosts various special events, including the Ulichnaya Eda street-food and 'White Nights' music festivals, and is open seven days a week.
