Kuroiwa curry, to eat and to take home

Recently I quite often go to a curry place called Kuroiwa Curry Hanten ("The Kuroiwa [name of the owner] curry shop"). They only serve Japanese curry, but it is very good. They now also apparently sell curry in bags that you can take home and just heat up in boiling water and eat at home. I got two bags as a free sample. They had a slightly different taste, but were very good too.
