Albertine Books
While it's not Shakespeare & Co., Albertine Books is as close as you're going to get to French bookstore heaven here in the states. Literature-loving Francophiles (or even those of us looking to brush up on the language) can get lost among the bookshelves of this whimsical Upper East Side shop - tucked into the historic Payne Whitney mansion! - for hours. And that astrological ceiling? Très fantastique!
