Suwim is a proper shophouse restaurant that sells a very standard Bangkok-style take on khao mok kai (shown above): rice with very little dried spice flavour served with an exceedingly sweet dipping sauce.
Although inoffensive, it's not really worth seeking out.
Better yet, go around the corner to Ran Khao Mok Kai Lek, which although it's located on the street, serves a more interesting version:
The rice, which they claim to cook using an old recipe, is slightly moist, with a subtle dried spice flavour. I chose to go with deep-fried chicken, which was crispy and tasty, if a bit dry. If you visit at lunch, you can expect a line here; the tart chicken and beef soup are as popular as the khao mok.
