Try the bag lunch when you're in a hurry. Zingerman's version of fast food: a simple sandwich on a crusty French baguette, side, drink AND dessert. (Rice pudding mmmm)
If you get gelato, be sure to ask if it's a premium flavor. They cost more, but all the prices are for regular flavors, and you will get a surprise at the register. This has happened to me twice now.
Very disorganized. You have to remind them of your food order when ordering from the café. By the time you finally get it, your coffee is already cold...I still come back because the food is good.
