This was my first stop after my plane landed at PHX on Sunday afternoon.  After I managed to get lost about 20 times in the huge Scotsdale Fashion Center, I finally managed to find the little blue window for Modern Burger.  I picked up two sliders and a side of fries.  The have two small tables right next to the ordering window, so I was able to dig in right away.  I thought the burgers were really good, which is impressive since I don't really like American cheese.  My leftovers were still delicious the next day after being warmed up in my hotel microwave.  Definitely worth the drive!
