America might run on Dunkin' Donuts, but Miami sprints on café con leche. Basically, as soon as you're weaned off the bottle, you're given this stuff — one part superstrong coffee, 20 parts warm, sweet, comforting milk — thus conditioning an addiction that eventually becomes a dietary staple for most of the 305. Serving it dulce y clarito is Coffee Zone in Brickell. The secret to its café con leche's beautiful flavor and wonderfully creamy, frothy texture might be the fact that the restaurant is hidden inside the same building that houses the Venezuelan and Colombian embassies. You have your choice of three sizes, with prices that range from $1.87 to $3.27.
