A single shot of espresso at PublicUs may cost $3, with a pour-over hitting you in the wallet for $6. But when it hits your taste buds, you’ll understand why. Cole McBride, the head of the coffee program and second-place finisher in the 2015 U.S. Barista Championship, uses green beans roasted by Velton’s Coffee, so you know you are getting some of the finest coffee in the country. Still don’t believe the cup is worth the cash? Even the brewing machine is work of art: The Kees van der Westen Spirit Tripplet is arguably one of the best espresso machines in the world. 1126 Fremont St., 702-331-5500, PublicUsLV.com.
