Panera at three weeks out?
My advice go there a few days before and have the soup you think you will be having that day make a trial run. That way you wont have any surprises at the shower.

I had the chicken noodle about 10 days out but I asked for mostly broth when I ordered...this may be a little different since you will be at a baby shower. I have had the black bean in the past and it's good and the broccoli cheddar is my favorite! Panera is one of my favorites, I only go when I feel like a splurge! Good Luck!!
