Customer service is very mediocre. This has happened twice now, where I've called to ask if they have a particular soup i like, that they only have on certain days, and both times the lady i talked to said they have it.
When i got there, they rung it up for me, only to tell me later that they didnt have it available that day, so i got my money back and had to go somewhere else.
I dont know how hard it is to check or if the employee both times just did not care enough to look, but because of that i definitely recommend a different Panera or different place to eat altogether.
