Panera Bread is a big bakery chain in the US; people love this place. I really do not get the hype. Yes, the baked goods look good but they taste average. Their sandwiches are not bad yet not great either. Their locations do have free wi-fi. Oddly enough, during peak time for lunch between 11:30am - 1pm, wi-fi access is limited to 30 minutes! I found out about this policy after speaking to one of the servers; it is not posted anywhere!
Plus side, service is quick. If you are in the Square One area, Panera Bread is worth checking out if you have never been.
