Consisting of little more than a brick floor with a tin roof over it, Tapui claims to be the first shop in Sukhothai to have sold the city’s namesake dish, gŏo·ay đĕe·o sù·kŏh·tai (Sukhothai-style noodles). It's located about 1.3km west of the Mae Nam Yom; there's no Roman-script sign or English menu but there are pictures to guide your choice.
