Thursday Night Throwdown, a "Latte Art" competition between baristas, held at Cafe Virtuoso.
There were brackets--first round of 16 made a heart, second round tulips, third rosettes, fourth (and final) freestyle. You can see the contest in action up there: the baristas put their cups down and the judges pointed at the winner.
It was packed. They were serving cortados (delish). There were bags of unroasted coffee. And some hipster folks. A good time was had by all!
