Potbelly Sandwich Works is an outstanding restaurant/deli with a great menu. While staying in National Harbor, my family ate here for five different meals (it really was the best place to eat in the entire area). There was something for everyone and even some items I have not seen in other restaurants (I am referring to the succulent mushroom melt sandwich--warm mushrooms with melted cheddar on a crusty wheat roll, with tomatoes and Italian seasoning--amazing!).
Since you bring your own items to the tables, there is no tipping (a money saver). The speed at which the food was prepared was very quick even though everything is made fresh to order. The soups were terrific and the desserts looked great, but we were too full from our meals to have any.
Potbelly is right on the Potomac, so it is a beautiful area to walk around after your meal. And, it is right next to Ben and Jerry's if you have room for icecream later (but you probably won't).
I wish there was a Potbelly near our home as this would be a regular "go to place" for our whole family.
