Mediocre food at the grab and go area in the airport. Unreasonably slow service! I picked up a chicken csaesar wrap (pre-made) and bottle drink. 2 people in front of me. First one took 5 minutes (no exaggeration) to place the order and had to wait for her soup another 5 min. (wow). Next person paid with cash and it took another 3-5 min to pay. She ordered a banana and chips. Next it was me. I paid with a credit card and it took a reasonable amount of time. How this place will stay in business at this pace in an airport is beyond me? Oh and while I was waiting another 5 ppl queued up and were waiting to order. I wish them luck because I'm a fan of the sitdown restaurant in Tysons. Just pick up the pace and be a lot more sensitive to customer needs please...
