The story
Restaurant Mosaic opened its doors at Château des Tesnières in Torcé, near Vitré, on 1 May 2025, marking a significant new chapter for Chef Chantel Dartnall. After fifteen acclaimed years in South Africa, the restaurant has found a second home in the French countryside, where the rhythms of the seasons and the surrounding gardens, woodlands, and terroir deeply resonate with her culinary philosophy.
Chef Chantel Dartnall’s cuisine is botanical at its core. She draws on a profound respect for nature, seasonality, and the beauty of exceptional ingredients. Her dishes are built around delicate herbs, flowers, and botanicals that are never mere garnish—they become essential components that invite guests to connect with the natural world. Inspired by French masters including Michel Bras and Alain Passard, Chantel creates compositions that capture the essence of each ingredient, aiming to evoke wonder, reflection, and delight. The experience is holistic, engaging all the senses.
Restaurant Mosaic offers a seasonal tasting menu that reflects the chef’s meticulous approach. Guests can expect a harmonious interplay of flavour, aroma, and texture, where each course is designed to nourish both body and soul. This is a cuisine deeply attuned to the earth, the forest, and the sea.
The restaurant’s wine program is equally distinguished. It has been honored with a Wine Spectator Best of Award of Excellence in 2025, recognizing a cellar of exceptional breadth and vertical depth that makes it a destination for serious wine lovers. The list also holds a three-star accreditation from the World of Fine Wine.
Restaurant Mosaic’s new home, Château des Tesnières, provides a fitting setting for this elevated dining experience. The restaurant serves lunch and dinner in a space that embodies the elegance and tranquillity of Brittany.
