Mastard: Simon Mathys’ convivial neighbourhood address

Awarded one Michelin star, Mastard is the warm and welcoming neighborhood restaurant of chef Simon Mathys and his partner Vicky. Tucked away on rue Bélanger with just 54 seats, the restaurant showcases Quebec’s terroir through refined techniques and bold, expressive flavors. Intimate, ingredient-driven, and full of charm, it’s one of Montréal’s most talked-about culinary destinations.

Opened on January 6, 2021, the project marks a turning point in Mathys’s career, following his notable departure from the now-closed Manitoba restaurant. Mastard reflects a deeply personal and confident culinary vision, where each service becomes an opportunity to celebrate the richness of local ingredients in a lively, authentic atmosphere.

Why the name Mastard? The chef-owner explains with a smile: “In the dictionary, it means ‘big and brawny’. I thought it was funny — so I decided to name my restaurant that.”

The menu is ever-evolving, with one guiding mission: to let the local shine. At the moment, guests might begin with a ham broth featuring celeriac, brown butter, and herbs. For the main course, a braised chicken is served alongside caraway cabbage, mushrooms, and smoked sour cream. And to end on a sweet note: rice pudding with apple.

It’s a delightful teaser — and leaves you eager to discover more.

The house also offers a thoughtful selection of privately imported wines. Simon himself curated the list, with a strong focus on natural and biodynamic producers.

A delicious address well worth discovering!
