Interesting concept was only positive. The food was terrible with minuscule size portions and high price. Pork sliders were 2 bites each with a couple of slices of pickled carrots as garnish. My sandwich was very dry with no aioli as told on the menu. When I asked for mayo I was told they had just run out. The service was terrible. Had to ask for water 2X and dishes were never cleared. My wife's food arrived 20 minutes after mine.
The iPads might have helped with problems on the wait but connectivity was an issue 50% of the time. This was one of the few times I was glad food was served on the airplane.
