felixgrantham The FRICK! http://www.frick.org/visit It's a house, built around turn of the century, taking up a full block next to Central Park with the family's fabulous Art Collection. Absolute Magic!

Cathedral of St. John in Harlem http://www.harlemonestop.com/organization.php?id=275 is also fabulous if time allows.

Also - Chinatown for food and great decorative accents!

If you're going, check out 1/2 price theater tickets the day of the show at TKTS TKTS (the line is long, but it only takes about an hour) - second location on Wall St. has a very short line if you're staying anywhere near.

cynthia scarlett Thanks so much for this post! Great ideas and it so helpful to have the address, where and how to enter some of the more obscure sites, and fantastic array of not so common sites!
