There are worse chains and worse fast food joints than Panera. But I'm not a big fan. This is a particularly large franchise. Fairly busy, and has an unfriendly atmosphere. The can't give a s&%! attitude of the staff contributes to this problem. They seem pretty unhappy, suggesting either that it's a poor work environment, or they hire or train badly.
They botched my order, acted like this was my problem, and more or less threw the bag at me when it came up the 2nd time. I'm giving them 2 stars rather than 1 because the reincarnation of my order actually tasted alright, though I had to rush to eat it because it was so late in arriving.
Bottom line - if you have mediocre food to start with, good service is pretty much mandatory. This joint needs to get its act together.
