I've been struggling with a question that a friend (who is very much DC savvy) asked me recently. After Breadline--I think most would agree this is the city's best sandwich spot, quality of bread, etc.--what's the next best option? My fear is that everything else blends together in a mediocre mass much behind breadline but hopefully I'm forgetting something. This is very much a chowhound question--so can't be any type of chain unless maybe a smaller local one. Different way to think about it: you're headed to the airport for a long flight and it's Saturday (so Breadline is closed). Where do you go to get carry-on sandwiches that'll take your mind off the horrible state of air travel and airport food?
