About Bangkok
Bangkok is sensory overload — street food, floating markets, golden temples, rooftop bars, and chaos that never stops. It's hot, loud, and the traffic is legendary. The food is world-class (pad thai, som tam, boat noodles), and everything is dirt cheap. Use it as a base for Chiang Mai, islands, or Cambodia.
