Au Bon Pain is my go to place at the Philly airport and downtown Pittsburgh. I love their pre-made salads! I usually go for the Mediterranean chicken salad. I've heard their soups are tasty but I have yet to venture there. I've had their breakfast sausage/egg sandwiches on asiago bagel! WOW!! filling and super tasty. Remember to ask for vegetables and cheese on it. Try their jalapeno MAYO!! Tasty!!
I would highly recommend this place for lunch and for people on the GO!!
