For a fast, healthy and fairly inexpensive option for lunch at the Scottsdale Quarter, I would say this is the place to eat at.  They have a simple menu as well as fresh baked goods all out on display making it easy to order.  I like the fact that you are not served at this restaurant.  You go up to the register order, pay and wait for your food to be brought to the table.  C3 serves the same food as Chloe's Corner across the street in Kierland.  I often order the salad and sandwich combo which has always been fresh and good. \nThey now have a frequent customer card that tally's up points every time you purchase something.
