Sightglass Coffee's opening day was yesterday. Owners Jared and Justin are "super nice," according to Yelp. And their brew? Is billed as "artisan." And, from what we hear, pretty damn fantastic.

Be sure to check out Sightglass Coffee at 270 - 7th Street, between Howard and Folsom.

But the place is not "fully open," it seems. According to Jon Bauer, "Sightglass is scheduled to fully open in September, but they are now serving a delicious custom blend from Verve Coffee Roasters. Sightglass will be one of 3 places on the planet to have a Slayer Espresso machine - they say that this espresso machine enables 'discrete pressure control across the brew band.'"
