We don't get out to Key Biscayne often enough. Any of us. So make a trek to Whiskey Joe's, which feels like a little piece of island bliss -- it is technically on an island, anyway.. Sip a frozen mojito, a piña colada, a rum runner -- or pretty much any other frozen combo you can dream up ($7 to $9). In the words of the world's happiest cliché: It's 5 o'clock somewhere.
