Original Isan dishes from northeastern Thailand are the specialty at this very international Thai restaurant (they have branches in New York, Beijing and Ho Chi Minh City as well as Tokyo). Squeezed into the bustling Toranomon Yokocho complex, this is essentially a mini-branch of the restaurant, serving a couple dozen representative dishes from the larger menu at their Yoyogi branch.

While there are a few items that will be very familiar to Tokyo Thai restaurant-goers, (Tom Yum soup, Massaman curry), the focus is mostly on original versions of Isan dishes like Tom Saap Kra Dook Aon (spicy Isan pork-cartilage soup), Nam Tok Moo (spicy grilled-pork salad with roast minced rice), Pad Pak Boong (stir-fried morning glory) and a couple of different kinds of Isan sausage. Ingredients are fresh-tasting and spicy salads pack a punch.

They serve four different variations of the shop's namesake spicy papaya salad - fewer than the Yoyogi branch's eight types, but still impressive. White and black sticky rice and boiled rice noodles are refreshing alternatives to the usual jasmine rice, which is also available. Despite its small size, the menu is fairly varied, and it's worth exploring to find your own favorites.

Drinks include Singha beer on draft and house wine by the glass from Y450. You can also pick up a bottle from the wine cellar of the nearby Hand Picking Wine bar to drink here. Budget around Y3,000 for food and drink at dinnertime, and Y1,000 for lunch. A limited take-out menu is available.
