Pasgianos. Nuff said.
Just mention Pasgianos (pronounced biz-ya-NOSE) to any Sudanese and they will know what you're talking about. That is, if they don't starting drooling first, or get a sudden bout of nostalgia.
Pasgianos is hands down my favorite soda pop on earth.
And it's only available in Sudan.
I'll let this story tell you more about it.
