Ordering from an iPad was pretty cool, though it took a while for the burger to come out and it costed a lot (though that's to be expected at an airport). It was a pretty good burger but the patty wasn't super juicy or anything (I work near Burgers Priest and P&L so I have high standards).
The staff are pretty aggressive about cleaning the tables and spend quite a bit of effort to make sure everything is spotless. It's nice, but I'd rather not have to smell Mr. Clean while eating my burger.
