as I'm currently located in Prague (start to live my life here in the city of my family origin) and try to escape as much as possible and find nice places for a chat and good coffee, you can be sure, that you'll find in the next time some other coffee shop reviews;)
At first I visited during christmas the La Boheme Cafe (which is also located in one of my fav' Prague districts - Vinohrady).
The coffee (I've ordered my fav' of all coffees - a cappucchino) is freshly brewed and made of high-quality coffee beans, including a glass of still water on a silver plate;).
I would highly recommend this lovely place if you're on a trip in Prague, locals or even if you wonder where to go for a good cup of coffee - La Boheme Cafe is one good answer!;)
