Osmium is Dark Matter Coffee's Lakeview cafe. The west side roaster opened up here to fill a void on a somewhat unremarkable swath of Belmont Avenue. Despite being on an "in between" stretch, this quirky coffee bar is a great hangout and is always buzzing. The coffee is unpretentious, refilled for free, and damn good. And they stock Do-Rite donuts daily. The interior embraces kitsch, and the back patio can accommodate a small army. As a roaming freelancer looking to borrow wifi, it's tough to beat.
