Every December springs (winters?) anew a row of tents selling Christmas baubles along F Street between 7th and 9th streets, on the south sidewalk of the Portrait Gallery, and every year the corner tent at 9th and F sells food. Last year it was Korean. This year it is empanadas (plus a couple other options, maybe), and they’re pretty good: thick flaky golden masa pastries stuffed with a variety of filling options, I tried chorizo and it was tasty though it seemed more like ground beef than chorizo. Other choices include chicken, I think spinach, a few others. $4 a pop seemed high at first but they’re big, easily twice as big as the ones you get at most empanaderias, and so a reasonable value. Not a bad way to keep a hand or two warm as you wander the rest of the block.
