More of these restaurants are popping up in airports. it's a convenient place to go for a bite if you're travelling alone or have less time to spare. the seats are designed to be pretty antisocial - an iPad in front of every table and a credit card slot in between.
you sit where ever you want, order on the iPad, pay, and the food comes soon after. I was travelling with someone else and decided to sit next to each other instead of across so we didn't have iPads in the way.
in terms of food, it wasn't too bad for airport food. while the selection is limited, the burger had decent buns, although the Mexican burger was lacking in jalapeƱos. it's also a nice spot to fit in your last routine before you fly off to USA!
overall I would come to a restaurant like this at a restaurant compared to the traditional kind. speed and convenience is everything at the airport.
