There's art, books, a view, a card game, and a public toilet — a darn clean one at that. Life doesn't get much better. Perched in the clouds in the Spanish-style plaza atop the Miami-Dade Cultural Center, a set of often-sparkling public restrooms connects the county's main public library and the ever-evolving Miami Art Museum. It doesn't seem to matter that the homeless population is wise to it. The place remains free of nastiness, stray papers, and your usual public shithouse detritus. So head downtown, drink in some art at the museum, borrow a book at the library, and sit in for a round of cards with the boys on the patio — then head to the head and spend some time relaxing in the only place modern man (or woman) ever finds peace.
