Chef Thitid "Ton" Tassanakajohn opened Le Du in 2013 with a straightforward premise: Thai ingredients, treated with respect and technical precision, can stand alongside any cuisine in the world. The restaurant's name comes from the Thai word for "season," and the menu rotates to reflect what Thai farmers are growing at any given time. That commitment to seasonality and local sourcing has earned Le Du one Michelin star (held continuously since 2019) and the No. 1 spot on Asia's 50 Best Restaurants in 2023. In the 2025 global list, Le Du ranked No. 30.
Chef Ton's path to the kitchen took a detour through finance. He studied economics at Chulalongkorn University, completed an MBA at Johnson & Wales, then enrolled at the Culinary Institute of America in New York. Stages at Eleven Madison Park, Jean-Georges, and The Modern shaped his technique before he returned to Bangkok. Today he runs several restaurants, including Baan (traditional Thai) and Nusara, which ranked No. 35 on the 2025 World's 50 Best list. Le Du remains the flagship, a modern Thai restaurant in Silom, Bangkok, where seasonal produce drives every course.
The approach is not fusion. Chef Ton uses French and contemporary techniques to amplify Thai flavors rather than mask them. Underappreciated Thai ingredients get center stage: regional herbs, heirloom rice varieties, and produce sourced directly from small-scale farmers across the country.
You choose between a four-course or six-course tasting menu. Groups of more than five are required to order the six-course option, and everyone at the table selects the same format. The space was recently renovated, with a striking ceiling installation of 20,000 glass test tubes filled with curated Thai seasonings, designed to evoke seasonal landscapes. It is refined but not stiff.
Service is led by Khun Tao and the front-of-house team, who walk through each course with context on the ingredients and the region they come from. A certified sommelier manages the wine list, which leans toward smaller global producers paired to complement the Thai flavor profiles. Expect a pace that lets you sit with each dish. Dinner service runs Monday through Saturday from 6pm, with lunch available Thursday through Saturday starting at noon. Reservations are essential.
Le Du's reimagined Khao Chae turns a traditional Thai summer dish into something unexpected: jasmine-scented ice cream paired with pork pate, shrimp, and pickled radish, balancing sweet, salty, and floral in a single course. The Massaman features aged duck, sous-vide and seared for a crispy skin, served over purple sweet potato puree with grilled potatoes, cucumber ribbons, and a tangy cucumber gel. River Prawn is a signature add-on worth ordering: a large river prawn with crispy scrambled egg and tom yum prawn paste sauce, set on black organic rice from northern Thailand cooked in a risotto style with shrimp paste, topped with pork jam, shallot, green mango, and long bean. Grouper paired with ant eggs represents the kitchen's willingness to push boundaries while staying rooted in Thai culinary traditions. The Crying Tiger, a refined take on the northeastern grilled beef classic, rounds out the roster of dishes that keep regulars returning.
Le Du sits on Silom Soi 7 in the Bang Rak district, a four-minute walk from BTS Chong Nonsi (Exit 4). BTS Sala Daeng and MRT Silom are also within reach, about 15 minutes on foot.
