Dreaming Ant is unique, a venue (actually 2 venues) that make browsing for DVDs fun in an online era. The staff (especially the proprietor Dean) is extremely knowledgeable about the imports, cult, and documentaries that make their selection unique - as well as about more mainstream fare.
It's the movie selection, and the careful arrangement, that make browsing fun - you'll see movies here that you've never seen elsewhere, or even heard of, and right next to the one you've selected... even more that pique your interest.
Both the Oakland and Bloomfield locations are laid back, pleasant experiences - Oakland is a little more open, Bloomfield more crowded, but both give you the feeling of being in a local community of movie lovers.
Highly recommended: the documentary section. These aren't your parents' documentaries. Ask for suggestions and give a few a try.
