Next stop: Tokyo. 

Despite losing its New York Michelin star in 2017, Isaan restaurant Somtum Der's success continues to skyrocket.

The expansion of the chain to Ho Chi Minh City in 2016 and Bejing earlier this year cemented its international reputation. Now, the somtam specialist is taking on Japan, with a fifth branch officially opening in the Yoyogi Matsui building, Yoyogi, Tokyo, on Sep 13.

Khon Kaen-hailing restaurateur Thanaruek Laoraowirodge (also of Supanniga Eating Room) originally opened Somtum Der in Sala Daeng with the objective to steer Bangkok taste buds away from the sweeter somtam flavors they so cherish.

As well as the staple papaya salad, the restaurant has built its name on classic Isaan dishes like tom saeb kradook aon (spicy soup with pork gristles) and larb moo (spicy minced pork salad).

Somtum Der made headlines at the end of 2015 when it broke into the Michelin guide for New York with one star, though it's since been consigned to the guide’s Bib Gourmand section—Michelin’s list of restaurants which aren’t quite worth a star, but which it wants to celebrate for offering high-quality food at an affordable price.

Until that wave of homesickness hits next Tokyo trip, head over to the original Sala Daeng branch (5/5 Saladaeng Rd, Silom, Bangrak) to see where it all began.
