I like to use Groupons for food whenever possible. Before our DC trip I found a Groupon that would work for lunch on our museum day. White Apron Specialty shop serves up hearty sandwiches and is less than half a mile from the American History Museum.
For $13 we received two sandwiches, two bags of chips and two drinks. The initial plan was to share this between three people. (And we easily could have, the sandwiches were large.) But in the end we purchased an extra sandwich and shared the rest.
Daughter ordered the Brooklyn, I had the turkey Provencal and Sister ordered the Bronx sandwich. All were on huge sliced baguette with loads of toppings. Ordering was very quick! We snagged one of the last tables as it was pretty busy at 12:30. Lots of professionals grabbing lunch! All of us enjoyed our sandwiches and would return again!
