The Great Burger
Tokyo does have a bazillion or so great burger places, and this one – The Great Burger – is tucked away in the back alleys west of cat street, south of the Omotesando main street. Burgers are pretty decent, though Golden Brown is still my local benchmark...
It's a few blocks south of the Meji Jingumae subwy station, along one of the many backalleys just to the west of cat street. And here's the Tabelog page.
