The five stars are remembering that this is an AIRPORT RESTAURANT.
Man, what is there not to love. I was having a stressful trip and the last thing I wanted was another soggy pizza from Sbarro or a food-court burrito that rips apart as soon as you unwrap the foil.
This little French bistro had a relaxing ambiance. They had a great selection of food that you don't see at airports (as in, you can actually find new dishes to try that you haven't had before). And the food is good! Its relatively decently priced. I mean its expensive, but considering its in an airport...
The service was great and quick (important during a layover).
Maybe not quite 5 stars in the real world simply due to price but awesome for an airport.
