👉 Restaurant fumes are a common, often unnoticed byproduct of dining out, caused by cooking oils, grease, and other food residues that accumulate in the air. These odors can linger, creating an unpleasant atmosphere that may mask the true quality of the meal or even cause headaches and respiratory irritation for some diners. The intensity and persistence of these fumes depend on factors like ventilation, the type of cuisine, and cooking methods used; heavy, greasy dishes tend to produce more potent smells. While often a minor annoyance, they can significantly detract from the dining experience, especially in poorly ventilated spaces.
