The museum does have a nice restaurant inside the museum that many people seemed to like. There are all sorts of restaurants on Third and Second Avenue. I just tried Juicy Seafood on Second Avenue and it was wonderful. There is also Harbs and Tri Dim on Third Avenue in the low 80's that are both excellent for Contemporary Japanese food and Chinese food respectively. Jimbo's for a burger on Second Avenue is where all the locals eat from Sutton Place. There is no lack of restaurants in this area.

I agree, I have no idea but I'm sure they could help if you call them directly.

I went for free as part of Bank of America's Museums on Us program, but they have some kind of promotion where all tickets are $5 per person through September 29, 2016. If you're visiting after that, you can Google "Cooper Hewitt tickets" and their Plan Your Visit page will come up. (Sorry, TA won't let me post the URL.)

Hi There. The museum itself is not massive. There is a fair bit on show but if you have two hours you can pretty much see all of it. Let yourself go through and then come back to the things you want if you have time. They give you pens you can save the information on with a code to look at on the web later. So if you need to know more you can save it to review again. Enjoy it.
