It's the eternal Zen question: How many links does a chain make? In chef-proprietor Mark Militello's case, we think the answer is several, all located in the South Florida area. With the recent addition of Mark's CityPlace in West Palm Beach, "Trade-Mark" Militello has expanded the empire he began in North Miami, then moved to Fort Lauderdale, Boca Raton, and South Beach. Many chefs of his James Beard Award-winning caliber think a namesake restaurant is sufficient, but we know when it comes to talent, a single venue is only one hand clapping. But four -- now there's some real regional noise in the making.
