Finally got a hand on the most famous kebap in Berlin. It was 03.30 am and was still queuing, speechless. I found the things that made them famous was the pan-fried vegetables (biting to fried potatoes in the doner was like heaven), bread (it was crisp and tasted good), and sauce (sealing off everything). So I would say the hype lived to the expectation, but I would not queue in the middle of the day for 1-1.5 hours. So better to find odd hours if you want to enjoy Mustafa.
