L'union fait la sauce, French restaurant in Tourcoing, France
L'union fait la sauce occupies a converted industrial building with exposed red brick walls and provides both indoor seating and a garden terrace. The space retains its original character through visible structural elements that speak to its past use.
The building began as a carpentry workshop and spinning mill before its conversion into a restaurant. This transformation allowed the space to transition from industrial production to a venue celebrating regional French cuisine.
The menu draws from traditional northern French cooking with a contemporary twist, using local specialties like Maroilles cheese sauce in fresh ways. Diners can taste how the kitchen celebrates the flavors and ingredients that define this corner of France.
The establishment is located on Rue de la Tossée and serves lunch on Mondays with dinner offered Tuesday through Friday, with last orders at 21:30. Guests are advised to check ahead since operating hours are limited and advance booking is recommended.
The restaurant maintains a curated beer selection featuring Vedett IPA alongside an extensive wine list available by the glass. This beverage-focused approach means the pairing of drinks with food receives equal attention as the kitchen itself.
