I love the variety that comes with Panera. Their bagels are delicious, and their array of cream cheeses is also impressive. The sandwiches and pasta are also pretty good, though I've heard from people who've worked here that most of the soups and other foods are just thrown in the microwave.
I always get the mac and cheese bread bowl, which I've introduced to other people and they've been forever grateful!
Also, their selection of salads is wonderful as well. They are delicious, and I love that you can get half sizes of most dishes.
