1667 K Street NW, though entrance actually on 17th Street
A Noodles and Company is coming to 17th and K St, NW near the Farragut North metro. I believe they are shooting for a Feb. opening. You can see their menu here. They opened their first DC location in Woodley Park back in Dec. 2011. They also have plans on opening a location in Georgetown at 1815 Wisconsin Ave, NW.
