Every type you can imagine. They have a nice bistro just inside of the restaurant, and although not cheap, it was a great place for drinks while waiting for friends. I'd recommend Buddhakan or Gansevoort Market, depending on budget and inclination.

Normally, the admission is: Adults $25 Seniors/Students $18 18 and Under Free Membership costs $90, so you have to decide how often you would go, and you could then go any time and not have to fight the crowds on Friday. I personally would not pay less than $20 as an adult or $15 as a senior. It is an excellent museum in a good neighborhood, so you could go down to the Hudson while there. The museum cafe was reasonable and pleasant. The museum is definitely worth a visit, and to be honest, I made my first visit only recently and joined, despite the fact that I've been in the city since 1972!

yes there are a number if current installations of hoppers but not an exhibit.

We went on a Saturday and there weren't any significant lines then. I would imagine that it would be even better on a weekday.

Yes Tooker painting is on display October 2016

Hi Susan - boy are you in for a treat. Not only is the museum fabulous, but it is in the middle of the Meatpacking district, which is filled with good and fun places to eat. It all depends on what you're looking for and whether it's lunch or dinner. My husband and I loved the Gansevoort Market for lunch and really enjoyed Fig and Olive for dinner. I would suggest you take a look at Zagat's "best restaurants near the Whitney" page (apparently we're not allowed to post URLS in our answers) and then review the menus of the places that look good to you. And don't miss walking the full length of the High Line - one of my favorite places in New York!
