Pros: Cheap, big servings, easy system to buy your meal (ticket machine, choose your order....economy, business class, first class...cool), friendly staff....good water. Cons: A little salty. Not something I would eat every day. I gave it a 5 rating because it is unique and does not disappoint if you like black curry with tons of flavor and delicious rice. It has a particular flavor that one might have to get used to. Go Go refers to Hideki Matsui and the fact that he wore number 55 (which is go go in Japanese, or five five in English). The place opens at 10:55 a.m. and closes at 10:55 pm. I was stuffed with the business class curry. When I went there, they had a chicken cutlet curry special for 650 yen...delicious and recommended. I heard they also have a location in New York. Be a man and try the Champion size.....enough for 5 people, I think. Enjoy!
