Went in April 2019 with DH and 2 DC. Highlights:
Going up Top of the Rock - absolutely fantastic
Staten Island boat plus Ellis Island museum - and booking months in advance for one of the limited tickets to climb up inside the Statue of Liberty - it was so much fun!
Hiring bicycles to bike round Central Park. It’s huge, so much easier to see on bike than foot.
Broadway show (we saw The Prom and got upgraded!)
Breakfast at Tick Tock diner - classic American diner.
Jazz and food at Birdland jazz club (need to book). Loved it.
Bus tour - we usually avoid that kind of thing, for being too touristy (!) but actually it was a brilliant way of driving through the neighbourhoods we didn’t have time to see properly.
Lunch at this great outdoor food market called Smorgasbord in Brooklyn (it only operates on some weekends) - really fantastic, international food.
Researched “best pizza NYC” and chose one of the places which comes up on those kind of lists for one lunch - was indeed very good pizza!
Bagels for breakfast from a proper NYC bagel shop!
Also walked the Highline, which was fun. And walked over Brooklyn Bridge with a billion other people on an unusually scorching hot day in April (got sunburnt!). Katz restaurant was good for some authentic NYC Jewish food.
We worked out that it was worth getting one of the City Passes, given what we wanted to do when we were there - researched which was best value for us. I don’t recall standing in any extra queues, it just saved us money.
We didn’t do Ellen’s diner as it seemed pricey and ultra touristy. Looked into Tenement Museum but that also seemed v expensive for (I think) only a 45 min tour. Didn’t managed to fit in The Met. Didn’t want to do the 9/11 museum - we felt DC were a bit young.
Had lunch in a sandwich place near Central Park called Alice’s Tea Cup, where they gave the DDs fairy wings, sprinkled glitter on them, and the crockery was like a traditional tea room in England, but the prices were absolutely extortionate for nice, but fairly normal English afternoon tea type food, which sadly we only realised after agreeing to go there with an American friend, who suggested it! We each got a pot of tea, because they had a very fancy and very long tea menu, but each pot was something like $10. Never mind the sandwiches, which were $15-20 dollars EACH. Before tipping, taxes etc. So check prices very carefully!
We absolutely loved going and pretty much had a massive grin on our faces most of the time!
