Just felt it needed its own thread.
Need something at 4am in the morning? Medication? A watch? Money changer? Magazines? Toilet paper? Fresh beef? Minute noodles? Ritter Sport chocolate? Have you damaged your suitcase? Buy a new one! etc etc
We all have our Mustafa stories. And if you are a tourist and dont have anything better to do at 3am in the morning (or suffering from Jet-lag), every taxi driver knows the place.
What are your stories? What have you found? Best deals?
