Fav art bookstore in the city (and the world?). Great place for inspiration and reference art, both new and vintage finds. Not very cheap but mostly quite worth it.
For oysters & libations. The comprehensive oyster menu changes depending on what they can get that's fresh. If you know anything about oysters or just plain like them, this is without question the spot. Currently my favorite oyster (not always on their menu) is the Skookum.
