Cultural Tip
In France it’s considered polite to ask about allergies before a meal, especially when you’re the host or when ordering for a group at a restaurant. The informal « T'as » is common among peers, but with strangers or in a professional setting you should switch to the full form « Est‑ce que vous avez des allergies ? » to avoid sounding overly familiar.
