"I was reluctant to stop because the ride thru looked busy, but I was 7 cars back and was back on the road in less than 5 minutes. Nothing like customer service that is efficient and respectful of your time. Host 656 was friendly, thanked me for my business, and delivered truly extraordinary customer service. I ordered the pastrami sandwich, she confirmed all the blows and would not hesitate to order it again. I had a lot of articles from this place and never disappointed them. If you are in the mood for a great sandwich, stop and try Potbelly at Loop 336 and I-45."
