During the summer you can get lots of different things on the Corniche. There's corn, beans, the ice cream truck, fresh squeezed juice, you can smoke a water pipe, there are coffee vendors, and of course, kaak which is sold by men with bikes like this one.
As I've written elsewhere, kaak is a round bread with a hole in it like a handle. It's a common street food.
While I was there, I saw this man push his heavy-laden bike along. I still haven't ever seen anyone ride a bike like this.
