5 stars for a Taco Bell?
Context is key. Yes, it's Taco Bell and for the most part the food from this one is identical to the food from any other Taco Bell. Everyone knows what to expect from the Bell.
So the 5 stars are for the staff and management. They're always extra friendly, they're always accommodating to my bizarre recipe changes - the facility is orderly and clean and in the 100+ times I've eaten here I've not had an order mistake or any poorly made, spoiled or otherwise wrong food.
