This venerable establishment, located on the east bank of the Intracoastal under the bridge that carries NE 163rd Street over the water, might appear at first glance to be more Jersey Turnpike than old Miami. But don't be fooled. The Lagoon, a combination marina/restaurant, has been open for business since the Thirties, when goodfellas like Al Capone used to drop in for a nightcap on their way home from an evening of nightclubbing, illegal gambling, or maybe just whacking some guy. The times, the clientele, and the drink menu have all changed since then but the aura, like the old-fashioned knotty-pine décor, remains. Don't believe us? Drop in one evening and order a house specialty. One of the high-octane, tiki concoctions (we recommend the Suffering Bastard, so named because if you didn't feel that way before you ordered it, you will after you drink it). Then step out onto the Lagoon's waterfront deck. Take a look around. Dark. Quiet. Secluded. You'll almost wish you had a body to hide.
