Nai Uan Yentafo is a local noodle shop near Wat Pho in Bangkok that serves yen ta fo with pink broth and plain noodles. Bowls come with fish balls, squid, blood cubes and meat, and you choose wide or thin noodles or order a brothless version. Orders are written on paper by the customer, or by staff for foreign customers, and payment is cash after the meal. There is no air conditioning, so fans are used to cut the heat.
