More NY Beat Places
Do definitely check out readings at St.Marks Church-in-the-Bowery.
There is also a book called Jack Kerouac's Walking New York (or something like that). Its basically a Beat-themed tour guide to New York. You'll love it!...
And also try Gem Spa, on the corner of St.Marks and 2nd Avenue. Ginsberg used to hang there.
Another cool place is Anthology Film Archives, which has tangential beat connections through Jonas Mekas!
