I would definitely come back and take a walk with a boy on the Charles bridge in the evening – it was so beautiful I didn’t take any pictures. Here’s a picture of the street jazz band that perform there every day though.
Praga is the Art Nouveau capital – such great architecture – beautiful restaurants and cafes.
Great sculptures by David Cerny – I love art in public space that makes you very confused. Also check out his crazy website – http://www.davidcerny.cz
