Best Okonomiyaki in Tokyo.
If you do cannot understand Japanese writing, you would not think that this place is a restaurant from the outside. The facade of the building looks like it's a deserted and is no longer in use. As said, "do not judge a book by its cover".
Anyhow, you have to wait in line before you can enter because the restaurant is full especially during weekend. Interior is traditional,although I am not sure what other restaurant looks like. :) Guests will be requested to removed their shoes and place inside a plastic bag before you can sit on tatami with low tables inset with griddles in the middle.
Food is great although you have to cook it first by yourself. This add up to the excitement and hunger after falling in line outside for more than 20 minutes. Staff are most willing to assist you if you don't know how to cook.
Favorite Dish: Okonomiyaki, Yakisoba, Teppanyaki
