Like most everyone working in DC I did not grow up in the area. And like most everyone else I often get a hankering for a taste of my hometown. DC is an amazing food city and you can find things here you can't find anywhere else, but for all the DC food scene has to offer it is tough to find Philadelphia staples like cheesesteaks, hoagies, soft pretzels (not that super pretzel garbage), Phillies Franks, Tastykakes and water ice. Thankfully TWSF now lives within walking distance of Taylor Gourmet. Since 2007 two Philly expats have been serving authentic hoagies and chicken cutlet sandwiches out of three area shops. With sandwich names like Market Street, Columbus Blvd and Pattison Ave its enough to make any Delco transplant feel at home. They even import their rolls from Sarcones Bakery, if you're from the city of brotherly love you know what I'm talking about.
I am a big fan of their classic Italian hoagie called The 9'th Street Italian which in addition to an awesome roll includes genoa salami, capicola, prosciutto and sharp provolone. A hoagie will set you back about nine bucks, kind of steep but those rolls dont import themselves (heck, you'll pay 6 at Subway for public school quality coldcuts on a sponge) I highly recommend this place to anyone of the Philly Phaithful or to those of you who just want a good sandwich.
P.S. They recently opened a Rita's in Chinatown. Go Birds
