Participants will respond "yes," "no," or "I don't know" to the item: "Think back to the beginning of this survey. When you were looking at the Just Salad menu, did you notice any labels (other than calorie information or price) next to or beneath the food items?"

If participants responded "yes" to noticing labels, they will respond to "How did the label alone (not the calorie information or price) influence what you chose to order, if at all? The label…" with three options: more likely, less likely, or no effect
