If you're looking for a good burrito, this is the place to go in DC. Strictly a take-out place (they have a few tables), it's also hard to find, located in an alley off 19th St NW. Owned by the same people as C.F. Folks, you'll get attitudinal service but a terrific burrito to take back to your office. They're only open for lunch, it's always crowded and the hours are limited, but it's worth the wait. You can fax your order in ahead if you're in a hurry.
