I expected to hate HY because it's intended for rich people but, damn. Damn. That would be like hating New York itself. You can't hate something which is full of fun stuff. If you choose wisely, you can enjoy HY on your own terms, with or without money.
The biggest attraction is the "Vessel," a huge structure designed for walking and photography (my favorite activities). There are pics below. Entry into the structure is free.
Dining options are good and wide. I ate a delicious lunch at one of a dozen restaurants. There are a half-dozen nice coffee-shops. There's a chic bar in Neimann Marcus I'm keen to try.
Have you been to Hudson Yards? What was your experience?
