It is all about Rapid Check-In. Without it I would not frequent Panera that much. It just makes my life so easy and so simple. No lines, no waiting just order and pay online and BAM! it is ready when required.
I'll spare you on the food - you already know since it is a chain. No complaints. Always good and fresh and I am in love with the soba noodle bowls. Best thing they have ever added to their menu.
