Ive been in food service management for many years, and being a Panera GM was the WORST experience I ever had.
As a former General Manager, I speak from my position and from what I observed. Employees are treated like equipment. One of the first things a GM is told, is to get 3 (bad) "write-ups" on EVERYONE (in case you want to fire them). You are supposed to drill into their minds that "Its all about the bread" , and have the employees get in a group and chant "Bread is our passion, soul and expertise!" Quite embarrassing for all. If the day's business is slow, you have to send people home before they finish their shift (with no regard to the fact that these people need to make money). As a manager, expect to work 70++ hours a week, and spend more time making sandwiches and clearing the dining room, than running your "restaurant". Forget the bonus, the system is structured to make it impossible.
As an employee, expect very little gratitude. You'll be expected to learn ALL positions, make minimum wage, adjust YOUR schedule to fit theirs, get written up, and pretend you're have fun.
One of the main reasons I resigned, was how I was expected to (mis) treat the employees.
Its nothing more than a fast food place, with a few decorations.
