Opening in October 2011, this new 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 wooden sidewalk chairs and a bench in front. Even without the seating, it’s a wise choice for a new location — filling a void that many downtown patrons of decent coffee have lacked since the closure of Caffè Amici nearby. And they should clearly see this opening as a major neighborhood upgrade.

The shop is set up to impress, as they offer scale-weighed hand pours — weighing being de rigeur for getting your TDS right in a shop since about 2010 — 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.

They still seem to be dialing in on the quality of their espresso here, however, as it didn’t measure up yet to the standards at the Coffee Bar mothership. Using Mr. Espresso beans, they pull shots with a decent layer of a mixed medium and darker brown crema. The flavor is complex with an emphasis at the herbal pungency end. Served in black ACF cups.

Downtown SF not only again has good coffee, but the bar has been raised.
