FREE TACOS! (If you buy one.)
Pretty good deal at the new Pica Taco at 14th and Florida, through tomorrow it's buy one, get one free tacos. Worth checking out, as I've never been there.
I've also heard they're going to do two-for-one once a week as well.
Here's their Yelp page. They're at 1406 Florida Ave NW.
UPDATE: A commenter says it's one free taco with any purchase. So not actually two-for-one.
