Namsu × Fatboy Izakaya presents “Shanboy Izakaya” at Namsu, Soi Sangchai A One-Night Collaboration Bringing Shan-Japanese and a Touch of Thai Flavours to Bangkok’s Izakaya Scene

Rooted in a shared appreciation for late-night dining and convivial drinking culture, the evening brings together two distinct culinary identities and popular Bangkok Izakayas. Namsu’s exploration of the Burma–Thai–Yunnan borderlands — where fermentation, pickling, and layered acidity define the cuisine — meets Fatboy Izakaya’s irreverent approach to Japanese-inspired bar food, resulting in a menu that is both expressive and elevated.

The collaborative menu will feature dishes such as Kobujime Tai with Tokyo Nam Jim Seafood Sauce, Shan Oyster Nigori with sansho pepper and pickled mamuang hao, and Chicken Wing Shibari, a chicken wing stuffed with sticky kamameshi rice. Other highlights include Tuna Tartare Hashbrown with Shan Chimichurri, “Shroomy Skewers” featuring mushroom skewers with fermented tea leaf butter, peanut tofu and beef tongue skewers with mountain mushroom relish, and Crispy Pork Belly with Taro Leaf Furikake and Pickled Shishito.

The menu continues with larger and more experimental dishes, including Mala Shabu with a selection of fish, Fatboy’s Gobo & Gyu Nigiri, Kagoshima A5 Striploin with Beef & Wild Mushroom Bile Sukiyaki, Shan Kani Miso Pappardelle with Soft Shell Crab, and Shio Koji Lamb Chop Blood Rice Donabe with Coriander Yuzu Kosho. Desserts close the evening with Sticky Burmese Toffee Cookie with Yuzu Melt Ice Cream and Mimeng Flower Sticky Rice with Peanut Butter Ice Cream and Lychee.

The drinks menu, created by Hnin Pwint and Philip, includes cocktails such as Honey, Cheese! with gin, salted acacia honey, elderflower, and yuzu cheese foam; Sumo & Sesame with sesame-washed rum, clarified coffee, cacao, and salted miso palm sugar; and Blood & Opium with blended whisky, cherry, sherry, strawberry, and beetroot shrub. Highball selections include Whisky, Green Tea & Lemon Soda, Whisky, Sticky Rice Tea & Calamansi Soda, and Sake, Yuzu Kombucha, Pineapple & Sichuan Pepper, alongside a zero-alcohol Sparkling Yogurt with Yakult, cherry blossom, and soda.

Set within Namsu’s late-night space above Rangoon Tea House in Soi Sangchai of upper Sukhumvit, the atmosphere will reflect the collaboration’s intent: informal, social, and slightly chaotic in the best way. Guests can expect a flow conducive to seating, moving about, and socialising with shared dishes arriving across tables, and an environment that blurs the line between dinner and night out.

Shanboy Izakaya also signals a broader direction for both brands. As the first in a three-part series, the collaboration lays the groundwork for future exchanges, including a reciprocal collab by Namsu at Fatboy Izakaya slotted later in the year, and potential expansions beyond Bangkok.
