50 Hours in Tokyo: Old School Beef Restaurant

My previous experience with the legendary Asakusa Imahan restaurant has been limited to the gyu-don bento box sold at consignment stalls inside department stores or some of those ready-made sauces on supermarket shelves bearing their name. But this time, as I was finishing up shopping at Kappabashi just a block away from their original restaurant, I decided to drop by for lunch.
