It sounds like a bad joke -- fried chicken and waffles on the same plate. But Roscoe's is one of those places that you have to visit at least once to see how it works (and judging by the wait, it definitely works). This Hollywood institution's close proximity to CBS Television City has turned this simple restaurant into a kind of de facto commissary for the network. A chicken-and-cheese omelet isn't everyone's ideal way to begin the day, but it's de rigueur at Roscoe's. At lunch, few calorie-unconscious diners (and they come in all colors here) can resist the juicy fried chicken smothered in gravy and onions, a house specialty that's served with waffles or grits and biscuits. Large chicken-salad bowls and chicken sandwiches also provide plenty of cluck for the buck. Homemade corn bread, sweet-potato pie, homemade potato salad, and corn on the cob are available as side orders. Granted, the waffles are of Eggo quality and come with enough whipped butter to stop your heart, but the Southern-fried chicken is addictive.
