The Verdict: The human chefs hired to consult on the menu at Creator seem almost superfluous; their powerful and pungent house sauces overshadow the excellent grass-fed patty, which is ground to order, loosely packed and expertly seared by the machine. With its copper conveyor belts, sculptural blond wooden base and glass tubes stacked with fresh buns and gleaming produce, the burger bot is a marvel of engineering and aesthetics capable of churning out 120 burgers an hour. The room is clean and bright; the sourcing of ingredients is aggressively local. But the real promise of Creator is its value proposition: At $6 a pop, it offers a truly great burger at a fast-food price. The Experience: The first robot-staffed bar in the world, inside the Miracle Mile Shops on the Las Vegas Strip, is a twinkly-lit, garage-chic space.
