Swiss Butter

Swiss Butter, already popular abroad, lands on Rue du Faubourg Montmartre with a distinctly pared-back approach: the menu keeps things simple, letting diners choose between beef, chicken or salmon. Each protein comes with fries, salad and the house's proprietary butter sauce, a recipe at the heart of the brand’s social media stardom.

The Paris address continues the chain’s ethos of efficient service and steady pricing, both hallmarks of its international branches. A strong following on TikTok and Instagram has helped drive local buzz around its limited but carefully honed offer, spotlighting the steak-frites classic in a streamlined format. The restaurant opened officially on October 1, 2026.
