What are some unique date ideas for the city?

I’m looking to mix things up a bit instead of the usual ‘take a walk and eat sushi’ date, and figured you guys might have some ideas. Anywhere in New York City is game, and the dates will most likely be late afternoon to nighttime. A lot of dating suggestions tend to involve alcohol, so I should specify that I’m looking for non-alcoholic dates that do not include bars, taverns or clubs. We’re still in the early stages of dating, so nothing too romantic or sleazy please.

I kind of wanted to do the ‘blind restaurant’ meal that seems to have originated in Sweden, but NYC seems to lack these restarants. Shame.
