Curry rice with deep-fried pork
This combination of two Yoshoku dishes, curry rice and tonkatsu, was first served in 1918 by the restaurant Kawakin in Asakusa (this restaurant has closed, but in Iriya and Senzoku there are still several restaurants carrying this name). It was called "Kawakin-don."
The present type was born in 1948 in the restaurant Grill Swiss on the Ginza.
This is now one of the most popular forms of curry rice in the whole country. Delicious as it is, it is also a dish rather high in calories.
