My favorite place on Bedford Avenue, this bookstore has both new and used titles. If you're patient and look close enough, you can usually find a book that's worth more than they're asking. Not to mention their stellar selection of magazine titles. Good for design, art, photography, sociology, fiction, and everything in between.
The best underground shows you will find will have free pbr and models as far as the eye can see. They are rarely announced, so keep your eyes out for promising openings, especially with Milk Underground coming up.
Seasonal salads, sweet and savory treats, and great coffee. It's probably my most common lunch spot when I work from home and they also offer catering if I'm too nervous to cook but want it to feel homemade.
