This two-decade-old Taiwanese-style shabu shabu spot is a firm Thonglor favorite for its soup and chili-garlic dipping sauce. OK also stands out for the individual pots that each diner can season to their tastes, as seating is at two u-shaped bar counters. Befitting its Thonglor location, the decor is suitably modern and minimal, and the quadrilingual picture menu makes for a friendly guide even for the uninitiated.
