I chose this picture today not really for the beauty of it (it's difficult to take good picture there because it's dark) but to tell you about this bar. This is Vzorkovna but everybody calls it the Dog Bar because there is a huge dog wandering in the bar. This bar is probably completely different from what you know. It's in a basement (not rare in Prague) with several rooms. Each room is different: one with fusbal (there was a tournament the day I took the picture), one with wooden benches that go up to the ceiling and a big one with a stage where artist can come and play like they want. As you can see there are tags everywhere and it seems that there is no rules but the atmosphere is really great. Another particular thing is that you put money on a wristband at the entrance and then you pay with it.
If you have time during your stay in Prague, go check it out!
