the plaza it is located at is small and parking is limited, so that's one annoying point about going to japanese curry zen. the restaurant itself is quite small, too, so space is very limited. the service can be a bit slow and the waiters or waitress might have trouble understanding, but overall it isn't that bad. the food, though, makes up for all of this. it is simply the best curry i've ever had. i've gotten the chicken katsu curry, the beef curry, and the tonkatsu curry, and they all tasted great. i also like their croquette and curry pan, and usually order them when i go there.
