The holidays approacheth, and if you don’t have any plans you’d better get cracking — Christmas is just ten days away! Lucky for you, we’ve rounded up the best places to dine on Christmas Eve and Christmas Day, from highfalutin Manhattan tables to casual Brooklyn bistros. If you’ll be spending a far-flung Noel anywhere near our sister Grub Street cities, we’ve also tracked down festive meals in Boston, Chicago, Los Angeles, Philadelphia, and San Francisco. And since we’re feeling an extra surge of the holiday spirit, we also have you covered for New Year’s Eve and New Year’s Day. Plus: where to party after you eat, the city’s best Champagne cocktails, and how to cure your very first 2011 hangover. Don’t say we never did anything for you.
