What is the guest's responsibility when it comes to allergens?

The responsibility of the guest regarding allergens is to inform the staff of any allergies before ordering. This is crucial because the kitchen staff relies on this information to ensure that meals are prepared safely, minimizing the risk of cross-contamination and adverse reactions. By communicating allergies, guests help the restaurant provide a safe dining experience that accommodates their dietary needs.

While reading ingredient labels is beneficial, it is not practical in a restaurant setting where dishes may be prepared with various ingredients, and guests may not have access to all information regarding preparation. The other options suggest actions that do not ensure proper safety or awareness regarding allergens. For example, consuming food without restrictions or choosing only vegetarian options may not address the specific allergen-related concerns a guest has. Hence, proactive communication about allergies serves as the best line of defense for both the guest and the restaurant.
