I've been flying since the days that airport restaurants were generally considered a joke and you had pay for practically everything inside the terminal with cash.
Today, things have changed and it is more uncommon to get a bad meal in an airport than not.
Barrio Cafe in the B terminal at Phoenix Sky Harbor Airport is certainly better than your average airport fare (pun intended).
We had the guacamole and chips, as well as Burrito Pollo Poblano (chicken), and it was great. Service was prompt and attentive as well.
