There is a moment in the night, usually after the clock passes 3:00 a.m., when if awake, the body hits a crossroads. Either go to bed or push on to the dawn's first light. If the choice is to forgo sleep, sustenance is usually a must. For a hot meal there is no better place than the 24-hour 11th Street Diner. Whether it's pancakes or fried chicken, the diner serves quality food at reasonable prices. An added bonus for late-night owls is the possibility of a celebrity sighting. The proximity to South Beach clubs makes the eatery a natural stopping place for the famous. Recent hungry partyers seen chowing down include pitcher Livan Hernandez and rapper-turned-actor LL Cool J. (See, the famous haven't departed the Beach; they've just moved on to better and cheaper places.)
