Marrakech: Jemaa el-Fnaa
The most famous square in Morocco, the Jemaa el-Fnaa in Marrakech is also a UNESCO Masterpiece of the Oral and Intangible Heritage of Humanity. This place surely is unique and magic. During the day there are lots of juice stalls where you can buy a glass of orange juice for just 4 dirhams (40 cents!), there's also dates and nuts stalls, monkeys and snake charmers, who are always ready to surprise you with a snake around your neck - not my favourite, by the way...
As the sun sets - which I recommend you to watch on the terrace of one of the cafes around the square - dozens of food stalls start to settle in and you can see plenty of delicious Moroccan food being cooked. Just choose one of the stalls, sit and you'll be presented with bread, fresh tomate sauce, marinated olives and sautéed spinach. After that have a couple of chicken or beef skewers, some couscous and maybe a tagine - Moroccan kind of stew. Wrap up your experience with a stroll around the southern part of the square to watch the dancers and the musicians playing drums and flutes.
