Sweetgreen is a company most known for selling flavorful, expensive salads. When people think of salads, they typically don’t think “delicious”; when people think of “healthy fast-food,” they usually think it’s just a marketing ploy. Sweetgreen is one of the hundreds of chains that market themselves as a quick, healthy food option, but it’s been able to stand out from the rest because it actually delivers in its food quality and health promises.  When people eat at Sweetgreen instead of the burger joint across the street, they also feel like they’re making a conscious decision to be healthier version of themselves—satisfying the reflective level of Don Norman’s principles.
