Oseille
Rio de Janeiro, Brazil; Rua Joana Angélica 155, upstairs, Ipanema, Rio de Janeiro RJ 22420-030, Brazil
Oseille reduces the distance between dining room and kitchen to the width of a counter. Upstairs on Rua Joana Angélica in Ipanema, Thomas Troisgros welcomes a small group into a restrained room organised around the cooks' work. With sixteen places, the restaurant has an intimacy that allows the progress of a dish to become part of the evening's conversation. The tasting menu draws on French technique and Brazilian ingredients, reflecting a family culinary lineage while allowing Thomas his own voice. The name refers to sorrel and carries a connection to the celebrated Troisgros salmon preparation; it is a point of reference rather than a promise that the same dish will appear. Seafood, including cavaquinha in Michelin's account, helps articulate the restaurant's coastal context. One Michelin star in the 2026 Rio guide recognises Oseille's achievement. It earns its place among the city's best for turning an ambitious dinner into a focused encounter with the kitchen. Reservations are particularly important at this scale, and the current booking route should be checked before travelling. The address is the upstairs Oseille space, distinct from the restaurant below.
