Five minutes toward the river gets you to River City. Seven the other way, ICONSIAM. In between: a hardware shop that is older than the restaurant, a shrine that gets fresh marigolds every morning, and — if you are early enough — the smell of someone is breakfast rice on every corner.
Charoenkrung was Bangkok is first paved road, and the neighborhood still carries that sense of being first at everything, quietly. Shophouses that used to sell rope and lacquerware now sit next to design studios, but the street food carts have not moved an inch in decades.
We have never needed a sign that lights up. People find the smell before they find the address.
If you are walking from ICONSIAM, take the small soi past the old post office rather than the main road — it is a longer way in distance and a shorter way in time, since it skips the traffic light entirely.
