I'd recommend everyone who hasn't had Katsu Curry to try Kaiju.
Even though the store is not ran by Japanese people, the Malaysian cook and manager were trained at a Japanese cuisine school in Malaysia.
THE GOOD
1. Fresh and tasty. The food comes quickly, but is always prepared fresh. Your best bets are to go either very early at opening, or during the meal rushes for the freshest batches.
2. Cheap. The price is quite good, especially since traditional Japanese restaurants are quite pricey.
THE BAD
1. Hard to find for the FIRST time. Once you know how to get there, it's pretty convenient.
2. Deserted, sterile food court. It lacks the ambiance of a restaurant.
3. Presentation is mediocre. It's basically fast food, so the food isn't very pretty. Packaged in simply styrofoam boxes, served with plastic forks.
