Cultural Tip
In French-speaking countries, it is common to explicitly mention food allergies when ordering, as restaurants are required to accommodate dietary restrictions. Using 'allergique à' is the standard, but saying 'J'ai une allergie à…' is also perfectly natural. Be aware that some menus may list 'sans arachides' (without peanuts) for safety.
