Besides serving some of the best Bloody Marys in town -- rich, spicy and spiked with globs of horseradish and cucumber spears -- Williams Tavern offers a free, all-you-can-eat brunch for the hungover hordes every Sunday. But don't look for quiche or candy-ass eggs Benedict here. Instead, bartender Gina Ko dishes up a simple, tasty buffet of stomach-anchoring dishes like spaghetti and meatballs, homemade hummus and falafel, beef-and- bean nachos, even macaroni and cheese. Come for the booze, but stay for the grub -- there's no better (or cheaper) way to chase down that hair of the dog.
