Once the calendar flips, House staffers will no longer have to trek all the way to Union Station to feast on Pret A Manger’s gourmet goodies.

The British-based snack-monger has set up more than a half-dozen shops in D.C., and it plans to expand its reach on Capitol Hill by taking over the spot on 301 Pennsylvania Ave. SE currently occupied by the Cosi chain. Building manager Douglas Development expects Pret will be ready to take up residence “by spring 2014.”

Pret is best-known for its varied selection of healthful ready-made soups (carrot-ginger, Moroccan lentil), salads (beets and berries, wild salmon and quinoa) and sandwiches (cheddar-avocado-spinach-kale, turkey pesto).
