The coffee is the best thing there. But Every location is slowly as molasses in getting your order completed. It's twice as slowly when you're in a hurry. I either order ahead* and pick up my coffee or don't bother with Panera at all for this reason. Too many other options to deal with hard and/or too dense bread and slow service.
*Of course they had that recent security breach with customers data from online orders so I don't do that anymore..?
