Katsuya was definitely the highlight of my trip to Toronto. It was absolutely amazing! We passed by it on the first night and it looked super packed and crowded, so we came back the next day for lunch and it thankfully had open seats. There were also large windows and was brightly lit as a result.
Their whole menu is dedicated to Katsu. They had a variety of options but we ended up getting traditional Katsu, curry Katsu, carbonara Katsu, and a Katsu burger. They had various protein options for the Katsu too but we all got pork. The traditional Katsu seemed super authentic where you have to grind your own sesame seeds. The Katsu burger was the cheapest but was definitely worth the money. It was enormous and filled with cheese. Honestly, it was a bit overwhelming for me but my friend absolutely loved it.
I got the carbonara one and it was great. It was super creamy and filling. It had an interesting combination of bacon and seafood but worked well. The Katsu itself was amazingly crispy and tender. Definitely one of best Katsu I've eaten anywhere. Also super nice about the place is that it comes with free refills of miso soup, rice, or cabbage, but the Katsu itself was a huge portion so I didn't take advantage of the refill of rice or cabbage.
The service at Katsuya was very friendly and nice. All in all, it was an amazing restaurant and I would recommend anyone I know visiting Toronto to go there.
