Les Saisons (レ セゾン) is the flagship grand-maison restaurant of the Imperial Hotel, led by chef Thierry Voisin. It offers a classic French dining experience in a hushed, formal setting. The cuisine is rooted in traditional technique, particularly praised for its precise and deeply flavoured sauces, but creatively incorporates seasonal Japanese ingredients. Chef Voisin often greets guests personally, adding a personal touch to the formal service.
Diners consistently praise the refined hospitality, elegant plating, and the quality of the house-made breads and layered desserts. Standout dishes mentioned in reviews include an opening amuse-bouche of trout tartare with pistachio cream, and seasonal plates like sawara (Spanish mackerel) wrapped in a sakura leaf. The extensive wine list and sommelier pairings are also highlights, making it a popular choice for anniversaries, birthdays, and important business dinners. The kitchen can also prepare a well-regarded vegan course if notified in advance.
While most experiences are positive, a minority of guests have reported inconsistency. These occasional issues include dishes being oversalted or lacking flavour, instances of undercooking, and rare service lapses. Some non-Japanese visitors also found the staff's explanations in English to be limited.
Expect to pay around ¥13,000 to ¥18,500 for a multi-course lunch. Dinner menus typically start from ¥27,000; reviewers recently paid ¥32,600 for the "LE MENU DE THIERRY". A glass of Champagne costs around ¥3,600–¥4,000. For those seeking a memorable, formal fine-dining experience, the price is justified by the technique, service, and atmosphere. However, it may feel less valuable on the rare occasion that the kitchen or service has an off night.
