I went alone to Katsuya after work during their social hour. Between 5 pm to 7pm, the social hour has many of their dishes at half price. The sushi rolls are the same quality and size, however their sashimi are slightly smaller.
I ordered my food at 6:55pm and most of my good came out within 10 minutes. The food service was extremely fast while maintaining great quality.
My server was really nice and honest. I asked him that I have a certain budget, should I order off regular menu or social hour. He responded with social hour as they only reduce th price but not the quality of the food. I really appreciated his honesty.
I ended up ordering the nigiri sampler, albacore sashimi with crispy onion, the tuna taki roll, the tuna tataki with crispy onion, and the Sahara roll. Their rolls and nigiri were great (4/5), but their sashimi were amazing (5/5). The sashimi were just so flavourful and fresh.
In retrospective, I woild just order 4 plates of sashimi and one plate of the nigiri sampler.
I'd try this place again during social hour! Not sure how I'd feel paying full price as the menu gets fairly pricey!
