Mini Thai chain Lers Ros is adding another restaurant to the group, but it’s not just another location. News recently broke that owner Tom Silargorn applied for a beer and wine license under the name Esan Classic at the old Olive space at 739-743 Larkin St. in the Tenderloin, and Silargorn told Eater through a translator that the new concept will focus on Northeastern Thai Food. Silargorn was inspired by a recent trip to Thailand where he "tasted Northeastern food which all flavors hit his imagination to create a northeastern style in San Francisco," the translator said. Silargorn is teaming up with family member Chanon H., who will be cooking the new food. Northeastern Thai food, also known as Isaan or Esan food, is characterized by neighboring Cambodia and Laos influences with dishes like larb, khao soi and sticky rice. The duo is currently selecting wines, securing permits and remodeling the space for a hopeful late December opening. Stay tuned for more details.
