Mexico City, Mexico

Mexico City boasts the world's richest and most diverse street food culture, with over 600 taco stalls in the central market alone. The city is home to Quintonil, named the world's Best Restaurant in 2023, yet a meal from a street vendor costs as little as $1.50—a price point that is 30% cheaper than the average Thai street food portion in #4 Bangkok. This combination of Michelin-level dining and affordable, authentic fare makes CDMX more accessible than any other city on the list.
