I love Panera's salads and French onion soup. Yum! However, when it comes to eating at this location, I usually just order online so I don't have to deal with the extremely unprofessional employees.
Most of the time, the employees are grumpy, rude, and flat out don't care about the customers or the food. For instance, one time when I visited, the employees were passing around a baby in the food prep area, another girl was throwing things at another employee's backside (totally ignoring me as I tried to order at the register). I've had cold food more than once. A friend of mine had to witness the employees yelling expletives at each other as he ate. It has gotten slightly better recently, so I'm assuming they have new management and/or employees. I was given a few coupons for my poor experience after I called Panera's headquarters.
The restaurant is usually clean and they are efficient at getting orders filled quickly.
