Khao Tom Rim Thang

A roadside rice soup shop on Yaowarat Road that opens at 4.30 in the afternoon and keeps going until 1 in the morning, six days a week. The rice soup is only the base: the real meal is the southern Thai dishes from the wok line at the front, ordered one per person plus one and shared, with bowls of rice soup refilled all evening. When the Old Town's restaurants are stacking their chairs, this place is still filling up with locals.
