Tokyo is a city with wide variety of delicious local cuisines, but sometimes you just want the good old hamburger (especially hung-over on a rainy day)…. and that is exactly what this hamburger place offers.
The name of the restaurant is “The Great Burger” and the name completely stands for itself. Having been there several times (usually a bit under the weather) I highly recommend for those cheese lovers, the unusual gorgonzola burger. It literally melts in your mouth!! The avocado burger gets also a high mark in my black book and veggie burgers are also available!
The place is a bit difficult stumble into (although I amazingly did when I first found it) since it is in one of the backstreet of the Omotesando / Harajuku so make sure you got the map printed out. The lunch menu has discount. Lunch Time 11:30～16:00.
Shibuyaku – Jingumae 6-12-7 1F (渋谷区神宮前6-12-7 J-CUBE A 1F) [Map], [Homepage], open 11.30am-11.30pm.
