"Beef Aficionado" Nick has the story on his blog. A mixed review, but it's early still.
The patty had plenty of flavor and juice but just needed a little more fire. Despite some nice grill marks the surface was just a little light in color.The rest of the ingredients were wonderfully fresh however. With the line at Shake Shack being so absolutely incomprehensibly long these days (It is a great burger but I wouldn't wait for Kobe beef as long as some people wait for a burger) Goodburger is a viable alternative in the area. And I would argue that it is a comparable, albeit different burger vis a vis the Shack. Many I am sure will prefer the flame grilling cooking method, and I doubt the line will be as long.
