I really like Panera, but like Amy R, I've had a bad experience with this location. The service strikes me as being ill-equipped to deal with the crowds, and they can get a little fussy about any requests that are slightly out of the ordinary. For instance, I had a teabag in my coffee cup the last time I was in there, and I asked if I could get some hot water. The woman behind the counter really, really didn't want to get me hot water, and then she charged me the same price as she would have for tea. It was pretty lame.
That said, I have business in that area of town, so I kind of find myself drawn to the yummy sandwiches and free wireless.
