Thanks to Bryan for finding a real American-Mexican style burrito place in Tokyo! It’s called Frijoles but it might as well be Chipotle because it’s pretty much exactly the same, which is a very good thing here in Japan, also known as The Land of the Rising Sun and No Mexican Food.
The place is near Azabu Juban station which is a little far from where I’m living now, but it was well worth the trip to get a ridiculously huge burrito made exactly like they do back in the US. They even had spicy salsas and the green smoked chipotle Tabasco. The staff members also all speak English, there’s free refills on soda, and most of the clientele seemed to be foreigners. It’s like being in the US.
