I have only ever ordered delivery from Sacks as I work over on Rio Salado and Priest. I've had the Overture, the Symphony, and the Van Gogh. All of them have their special little attributes, and each is tasty in its own right. FAR superior to any sub sandwich chain in the area, and even some of the specialty sandwich shops which seem to cater to professionals lunching in the area.
Only once was the delivery not super quick, but it was due to traffic on the way to my office and not because anyone messed up. The sandwiches are always fresh, and if they show up a little soggy, I all it a testament to the freshness of their bread and vegetables.
I will continue to order on days I am not able to make it out of the office for lunch and recommend them to friends. Good stuff!
