Katz? Isn’t the real deal the Carneige Deli off Times Square? It’s like a classic. That’s where I’d take first timers.
It’s hard to go wrong in a deli on any main street in NYC.
The best museums. . . no competition. . .
The American Museum of Natural History
or walk across the park to the Metropolitan Museum of Art depending on your tastes. . . you can do one in the morning and one in the afternoon if you just focus on the highlights.
I’ve got it!
AMNH in AM, walk down to the Carneige Deli for lunch(or a quick cab ride), then back up to the MMOMA in PM.
