|This newer location of the Mission/Potrero Hill's Coffee Bar expands their reach downtown to something you can actually walk to. The space is small and can get quite packed in a rush, but it's clean, well-lit, and has a lab-like feel with its white countertops and lower cabinets. They offer no indoor seating, but there is a short stand-up window counter and a few (and growing number of) wooden sidewalk chairs and a bench in front. The shop is set up to impress, as they offer scale-weighed hand pours and espresso drinks from dueling two-group La Marzocco Strada machines. (To say nothing of the impressive baked goods from Sandbox Bakery.) To their credit, the menu is relatively simple and the options are focused. Espresso shots have a decent layer of a mixed medium and darker brown crema. The flavor is complex with an emphasis at the herbal pungency end. They can run a little long and diluted based on the barista, however, adding a bit of variance and suppressing otherwise solid scores. Served in black ACF cups. Downtown SF not only again has good coffee, but the bar has been raised.
