Bangkok, Thailand

Bangkok operates the world's largest street food economy, with over 30,000 vendors serving dishes around the clock. Pad thai, boat noodles, mango sticky rice, and crispy pork belly cost under $2 per plate from pushcarts, making it 50% cheaper than the average street meal in Tokyo. The Yaowarat Chinatown strip alone draws 100,000 visitors on peak evenings, outperforming #2 Taipei's Shilin Night Market in sheer volume of options and nightly foot traffic.
