Since Katsura (along with the whole of prince hotel) got bought out by new management, the sushi chefs upstairs have started their own restaurants.
I just ate at Aoyama (Vic Park/Finch), a new restaurant opened by former head sushi chef Endo-San and his wife. Don't go there for the atmosphere but try the truly amazing expertly made sushi. He uses the best quality fish but doesnt charge Katsura prices. We ordered Omakase in advance and it was something like only $60 per person!! I'm not sure if that pricing is fixed- I suppose it depends on what he makes, but for sure we felt undercharged!! We had octopus & kelp salad with homemade kyoto miso, an omlette-like dish laced with Uni soaking in broth, crab miso soup, sashimi, sushi and sweet melon just to name a few dishes.
The other young chef that used to work at Katsura is now working at Shinobu @ yonge/lawrence. I haven't tried it yet but his sushi at Katsura was also excellent.
Also heard that Sake (pacific mall) is actually starting up their own Omakase room with a Japanese sushi chef too. This is a trend i'm looking forward to!
