    Very disappointing experience. This location has been out of flatbread for two months and was also out of American cheese. On top of that, the women’s bathroom was out of order. We placed an advance order, the app showed the order as almost done, but when we arrived the employee had just started making the sandwiches. Between missing menu items, broken facilities, and inaccurate order timing, this visit was frustrating and poorly managed.
