Guatemalteca Tikal (Tikal Bakery), 4320 Annandale Road, Annandale, VA, 703-256-0020, usually opens at 6 am but check, also a bakery.
Great atmosphere, the food is OK but only OK. Try the soups. They have pupusas too. Assorted, scattered items, like Philly Cheese Steak. Lots of Central American drinks. I have yet to try the sautéed flower dish. A fun place, I wish I could push it more on the food side, but at the very least I am glad I went once.
