Whoa, a “Jeremiah Langhorne restaurant” is coming to the corner of 7th and L Street, NW!?! Prince Of Petworth August 15, 2019 at 11:45am Sweet! Thanks to Daniel for spotting this from a marketing flyer “it appears Langhorne (of the Dabney) may be opening a new restaurant.” Updates as we learn more. Ed.
