Taste of Prague: Coffee is roasted on site. Zdenek - one of the best Czech baristas. Nice and relatively large interiors, very local and sometimes busy place. Strong wifi in the front room gets weak in the back.
Taste of Prague: A small, cozy kingdom of Mr Karel, the owner and barista. Don't ask for sugar in your coffee - you won't get it. Great vacuum pot coffee, and Kopi Luwak if you like that. Famous tiramisu.
