Came from the US, opened its first branch in Japan on March 24, 2017. Located in the Omotesando area, which is always filled with people walking down the nice streets on weekends.
They serve very flavorful hamburgers, full of "Umami", different from typical American hamburgers. The patty is carefully done so it's super juicy inside, is tastful, and soft as a whole (almost too soft). I would understand it if some people say that they prefer traditional-style hamburgers better, though. And, it feels a bit pricy for the portion.
That being said, I personally like this different style of hamburgers a lot, so rate it highly.
