Only few steps from the Charles Bridge, in one of the most touristy areas of Prague, is a great café / bar, a place ideal for afternoon snack with some microbrewed beers and coffee from local coffee roasters. Run by locals, who opened it up with intention to primarily offer locals a great getaway from all touristy stuff nearby, it is a great escape from hustle and bustle nearby. Give it a try, you won’t regret!
P.S. – yes, they have no website, only Facebook page
