This place is true to its star rating; that being said, there isn't much better in this part of the airport, so it's a fine enough place to sit and get a drink, as service is kind and, even when they're busy, pretty punctual.
Unless you are starving to death and don't care what you eat, don't order food here. Everything is prepackaged (like in two or three other spots, too) and they only have sad little sandwiches or salads. If you're going to be here a while, take advantage of the 'order a beer, get a shot for $5' deal.
