A beloved promenade connecting Fifth and Sixth Avenues, Rock Center offers a great way to spend some time and is home to everything from Radio City Music Hall to the GE Building to NBC Studios and several fine dining establishments. (Del Frisco’s steaks are amazing; tel: 212 575 5129.) Art and history tours are often guided by some of the most colorful characters in the city, and, yes, a gigantic Norway spruce becomes the Rockefeller Center Christmas Tree each year, presiding over Charlie Brown-esque ice-skaters. Shop anywhere from Banana Republic to Godiva to Swarovski, and finish up with a trip up to the marvelous Rainbow Room, on the 65th floor of 30 Rockefeller Plaza (tel: 212 632 5000).
