I've worked in Scottsdale Quarter for 2 years now in one of the offices and I think C3 Kitchen is just what this complex has needed.  Casual place to grab a coffee or sandwich/salad.  I've had a couple of different lunches here and the food has been great, lemon chicken salad particularly good.  Good setting to meet someone for a cup of coffee to discuss business too (Press, a few doors down, is also a good coffee shop, but too small with tables on top of each other to have a private business conversation).
