If the cronut craze didn't fill you in on this, there's a good chunk of Americans who love waiting in line for stuff that's only available for a set time per day. And if you’re one of them, you’re in luck -- this 40-year-old hole-in-the-wall at Plaza Grande is only open in the mornings, 9 to 11am. Their seco de chivo, a goat stew, is unmatched in the city, but if a bowl of warm, liquid happiness is not your ideal vacation food, they make great ham sandwiches too. And that’s the slow-roasted, pork shoulder type of ham -- not sad deli slices. Eat it on the terrace for some quality people-watching.
