Ongtong is one of Bangkok's best-known spots for khao soi — the northern-Thai dish of egg noodles in a coconut curry broth, topped with crisp fried noodles and served with pickled mustard greens, shallots and lime. The Ari kitchen draws a steady local crowd for big, comforting bowls at neighbourhood prices.
Beyond the signature khao soi, the menu runs through northern staples — sai ua sausage, nam prik relishes, and other Lanna dishes — making it an easy, authentic lunch between coffee stops in the Ari sois.
