I always see this place listed on my Yelp homepage as one of the best food places in Toronto, so I made a point to try it out. It's just a fast food place in the basement food court of the Aura building, and it's not that busy, so you don't have to wait too long. The lady working at the cash register was soooo so friendly and such a sweetheart. When she found out it was my first time at Kaiju, she gave me a little cup with rice and curry sauce to sample. I ordered the chicken katsu which was like $8+ tax and comes with some coleslaw on the side. The portion was big for what you pay - there is a lot of rice, but also a good amount of meat/slaw. You will definitely be full.
I am not even exaggerating though when I say that the katsu was amazing. It was like a pretty big piece of breaded chicken cut into 6 strips, but I still wish there was more because it was so good. It was lightly breaded and perfectly fried to a golden crisp... soooo delicious. Their Japanese curry is apparently a homemade blend of over 14 ingredients including fresh fruits and vegetables, and it is also really really good, although I do not know too much about Japanese curry. I can say that it was indeed flavourful, but not in that artificial, overly salty, MSG-loaded way. It is just a tad spicy, and started to build up a bit for me towards the end, but it was still tolerable. They let you customize your level of spice if you want.
Honestly this place is a hidden gem, will be returning!
