I received 5 star service and a hot breakfast sandwich. Yes, it was greasy, buttery goodness, but it's fast food at an airport. There's nothing at an airport in Las Vegas that's good for your health (either physical or financial).
For $5.83 with tax, the panini melt is just a little bite that doesn't break the bank. Next time I'll see if I can't pay extra to have a slice of tomato added. Not that any of the calories from the sausage and cheese will count less. Maybe it's good that it's a small sandwich.
