My first real introduction to good Japanese curry was in NYC at GO GO Curry. Go means 5 in Japanese and 55 is the number Hideki Matsui wore while with the Yankees. While returning to Tokyo I found out that not only was there a GGC location right neat my hostel but that the shop was very popular in Tokyo with around different locations.
I asked the hostess girl which one to get and she recommended the big combo. It was DELICIOUS!!
