R-Haan is a two Michelin-starred royal Thai restaurant in Thonglor, Bangkok, where Chef Chumpol Jangprai has built one of the country's most decorated tributes to traditional Thai cooking. The restaurant opened in 2018 on Soi Thonglor 9, earned its first Michelin star in 2019, and was awarded a second star in the 2020 Michelin Guide Thailand. Alongside Sorn, it became one of the first traditional Thai restaurants in the world to reach two stars, a milestone that put samrub-style dining on the global fine-dining map.
Chef Chumpol, a winner of Iron Chef Thailand and a veteran of Thai kitchens for nearly four decades, built the menu around samrub, the communal spread of dishes once central to Thai royal and family tables. Many of the recipes he works with are drawn from heritage sources that had nearly disappeared from modern kitchens, rebuilt through research into indigenous ingredients, herbal balance, and the rhythm of a classical Thai meal. Every course at R-Haan is framed as a chapter of that culinary history rather than a standalone plate.
You arrive to a quiet, refined dining room where staff walk you through a multi-course tasting menu that changes with the season. Expect a structured progression of savoury, spiced, sour, and sweet courses, each arriving in traditional Thai ceramics and glassware that echo royal table settings. Service is detailed and unhurried, with your team explaining the origin of each dish, the region it comes from, and the herbs driving its flavour.
You should plan for a full evening rather than a quick dinner, and come ready to taste unfamiliar heritage ingredients alongside classics you may recognise. Reservations are strongly recommended, smart attire fits the room, and the kitchen can accommodate dietary needs if you note them when you book.
The signature experience is the Royal Thai Curry course, built on a hand-pounded paste and aromatic coconut cream that showcases the depth Chef Chumpol looks for in heritage recipes. The Roasted Duck with Lychee is another anchor of the menu, pairing slow-roasted duck with the sweet, floral lift of fresh lychee in a sauce rooted in old palace cookery. For the finale, the Grand Palace Dessert Set brings together several classical Thai sweets on a single tray, from delicate egg-yolk confections to jasmine-scented rice creations, served as a tasting in miniature. Beyond the plates, the samrub format itself is a highlight, letting you read each course in relation to the others rather than in isolation.
R-Haan sits at 131 Soi Thonglor 9 in Khlong Tan Nuea, Watthana, tucked into one of Bangkok's most established dining neighbourhoods off Sukhumvit Road. BTS Thong Lo is the closest rail link, with taxis and ride-hailing the easiest way in from central Bangkok.
