I worked here (the original Green & Wright location) for 3 years in college (well, 1.5 years at Delights in the Union before it closed, and the other 1.5 here) and holy crap I miss it.
The sheer amount of options here will blow your mind. You could eat there very single day for a year and not have the same thing twice. Za's offers pizzas, pastas, salads, and open-faced sandwiches. Unless something goes horribly wrong (or a customer suddenly remember that they are allergic to the sauce they ordered and we need to remake it), everything is usually ready within 5 minutes.
It's a busy, popular campus hotspot, and was responsible for most of my meals during my junior and senior years of college. Best place to work - ever.
