Says New York magazine:

Black Iron Burger Shop was created with a noble tool in mind: a heavy piece of ancient black iron that burgers would be griddled upon. But then owner Jason Hennings came up with an even more noble tool: an $8,000 Keating Miraclean griddle, a steel-and-chrome, thermostatically regulated monster that will be a lot easier on the small space than a black iron monolith would have been.

It opens today, according to the magazine.
