There are four ingredients that go into a great café con leche. First, of course, is the coffee. Second is the water that streams through the grounds. Third is the milk that cuts the bitterness with creamy goodness. The fourth ingredient is harder to define. Call it location, ambiance, or scenery. Whatever the name, a great café con leche requires a place to sit, sip your liquid crack, and gawk at the mélange of humanity around you. By these criteria, the top café con leche in town is served at the counter of La Sandwicherie. There is nothing finer than stumbling over to the sliver of a restaurant at 3 a.m. and ordering the steaming mixture of Medaglia d'Oro espresso and milk you need to drive home. Of course, there are also super rico sandwiches to sop up the booze in your system. While you're sobering up, feast your other senses on the strange, sexy beasts pouring out of Mac's Club Deuce next door and prowling 14th Street. This, dear Florida flâneur, is what life — and café con leche — is all about.
