Located on the 3rd floor of Gaysorn Amarin, Fatboy Izakaya sits right in the heart of Bangkok’s vibrant Chidlom district — surrounded by luxury malls, top hotels, and office towers. 

OVERVIEW

Fatboy Izakaya is a modern Japanese dining concept that blends Tokyo street-style energy with Bangkok’s bold, playful spirit. Designed for sharing and socializing, Fatboy brings people together over creative Japanese comfort food, inventive cocktails, and a vibrant, music-filled atmosphere.

The menu reimagines traditional izakaya dishes with modern twists and local influences, while the bar delivers signature cocktails, Japanese highballs, and curated sake that perfectly complement the food.

With its neon-lit interiors, warm wooden textures, and upbeat vibe, Fatboy Izakaya offers a dining experience that’s stylish yet unpretentious — where every visit feels like a night out with friends.

It’s Japanese soul, Bangkok attitude — all in one unforgettable experience.

AMBIENCE

Fatboy Izakaya blends Tokyo’s underground energy with Bangkok’s playful modern vibe. The interior features warm wood tones, moody lighting, and pops of neon color, creating a space that’s both stylish and unpretentious.

By day, it’s casual and welcoming — perfect for lunch or a relaxed catch-up. By night, the space transforms with glowing lanterns, ambient beats, and a lively bar scene, setting the tone for an energetic social dining experience.

The design strikes a balance between Japanese craftsmanship and urban cool, with open kitchens, bold graphic touches, and perfect seats that invite both small groups and larger parties to settle in and share good food and drinks.
