Marrakech, Morocco

Jemaa el-Fnaa square transforms into the world's largest open-air restaurant every night — over 100 food stalls serving harira soup, snail broth, merguez sausages, and lamb tangia slow-cooked in underground ovens. UNESCO designated the square as a Masterpiece of Oral and Intangible Heritage, a distinction no other street food city on this list holds. The tangia alone, cooked for 8 hours in a hammam's ember pit, embarrasses most braised dishes in Michelin kitchens by delivering deeper flavor and texture with minimal intervention.
