I agree with everyone else, skip the lines. They're full of indecisive families of ten.
Onto the food, I had a bbq flatbread and mac and cheese. The flatbread was average. The ingredients were fresh and tasty but the bread itself was cold and just very sad. The mac and cheese had nice flavor but the noodles were soggy.
Overall the food isn't awful and it's a nice clean place to eat, but with so many better dining options steps away (Cafe Zupas, Pita Jungle, Suace) , I don't see why you'd go to Panera.
