Efficient service, food cooked to order, tables available even at rush hour. The building works, and better do the people in the business. For those who care little about noise, the top floor has enough seats for everyone, even if larger groups are more difficult to accommodate for. I went downstairs, where the noise level dropped substantially. Since I was there to study, and so were most of the others down there, I may advise that you only go down there if you feel you need quietness. Take that as you wish. Anyway, it's Panera. They make sandwiches, soup, and bread. Good job to this particular chain.
