I had an hour and forty minutes on the ground in the Detroit airport, and managed to rustle up a grilled cheese in the McNamara Terminal. I had never heard of National Coney Island before, but a quick google revealed that they have 20 locations throughout Michigan. (Something about this seems less than “National” to me, but apparently no one’s policing this.) I was pretty hungry, so it kind of hit the spot. Truthfully though, it offers nothing special. It had a nice crunch on it, but whatever they grilled it with wasn’t all that tasty.  I gave it a 5, and as my mom is apt to say, “Well, I would eat it if I was starving…”   5/10
