Most people think of beef hamburgers when they think of P. Terry's; however, they happen to make a delicious chicken burger. Unlike most fast food chicken sandwich options, the P. Terry's chicken burger is made from boneless, skinless chicken breasts which are ground and formed into burger sized patties. Cooked on the grill when you order it, the result is a juicy and delicious chicken sandwich. And, if you opt to include the tomato slice (which I don't), you'll be delighted to know that their tomatoes are locally grown and delivered fresh every day.
Of course, it goes without saying that P. Terry's burgers and fries are awesome as well. If you are new to Austin and haven't yet been to a P. Terry's, I highly recommend a trip.
