Cobra, just a place for locals to drink. Opens 24 hours. No tourists here, so no English. Music was mostly heavy metal and in Czech. Not too loud. The bartender would dance to it. Two men danced with each other. When a young man fell asleep standing up, bartender looked at him to make sure he wasn't falling down then let him be. Suddenly, he opened his eyes and asked her where his beer was. She pointed to a table behind him. When later he fell asleep again, with his face leaning on an upturned palm, his elbow propped on the bar, she came by to stroke his hair very tenderly. When he woke, she gave him a cigarette and the nicotine kept him awake for at least another 45 minutes. When she shifted the ashtray, though, he got confused and flicked his ashes onto the bar.
Bartender yelled at another customer several times. Czechs are more animated than the Germans in Leipzig, at least. Maybe Bavarians are also like this. I've been to Munich.
Prague has quite a few of the permanently groggy, long time alcoholics, but I also saw a higher percentage than usual of the intensely thinking faces, faces of men forced into ceaseless mental activities or worries.
