We went for a day at the Metropolitan Museum last week. The Asian exhibit was very nice. And there was a great exhibit on Fashion, costumes mostly. It was a small exhibit, so you can see it all in about twenty minutes and have plenty of time to see more. Some good street vendors on the street outside the Metropolitan Museum and the entrance to Central Park.
I love the MOMA and it's all brand new. I haven't made it there yet, but the museum, I understand has free admission on Fridays between 4PM and 8PM....otherwise it costs $20.00.
As far as wandering around the city is concerned. There is no place to go with better street food and merchandise than Greenwich Village. Some of the best sidewalk cafes and coffee houses are here. Visit Bleecker and MacDougall Streets. It's a very nice corner. Lots of second hand clothing stores, especially around NYU. And the chess players in Washington Square park are always fun to watch. Sometimes on sunny days, you can see free performances many are high quality in the park. You can shop second hand books on the street too. It's also the place for off-Broadway, but also in the East Village.
A really fun show near NYU is Blue Man Group. If you go there, and you should if you can fit it in.......be prepared to be amazed and thoroughly entertained. I can see from their web site, the ticket sales are 16 weeks out......amazing. We saw it several years ago when it was newer. We bought tickets that day for the evening preformance. The theater was full, but I'm amazed that it's selling tickets so far in advance. It's worth the advance planning though.

Soho is very nice too, some great street fairs, but the shopping is a little more expensive....still there are tons of street merchandise of high quality. There are also some great flee markets in the West Village on Broadway (not West Broadway, but Broadway) and....well, I'll have to look at my map to give you the exact location, and on 8th Ave. somewhere around 23 to 26th I think. For those, I'll have to check too.
It sounds funny, but a good way to get oriented to the city is to buy a two day ticket to the double decker red buses with a tour guide. You actually learn a lot about the city, history, etc.... but you also see plenty of street life. And it's carefree and fun. You can get off and back on for two days all for one price.
There is so much to do here, you'll have no trouble at all staying very nicely entertained.
Unless you love sight seeing, I wouldn't go to any of the traditional sights. But that's me. I like to just hang out and watch people, taste the food and buy cheap stuff.
I have plenty of other suggestions......but that's all for tonight.
