Not bad a burger overall, there is potential that it could be a great burger. The brioche is soft and buttery. The combination of jamon, Wagyu and mushrooms is good. The Wagyu however was slightly dry, and wasn’t as fat as would Wagyu be expected, so lacking in taste and flavor of the beef. The Jamon was blend, in a way then the burger seems to be quite blend. The Rocket made the taste refreshing though it over powered the whole burger. Would prefer other vegetables to have a better beef taste. But still, a good burger and although the burger was quite big that have to be cut into halves, I can still finish the burger without getting tired.
