Hong Kong- Looking for "reasonable" GREAT sushi
For the really nice places you can probably get by around $800 to $1000 during lunch hour, but the best cuts are reserved for dinner patrons for the most part. You can look into Ginza Iwa (lunch, because dinner starts at $1800). There is also Ta-Ke in Causeway Bay that's quite good. Best to supplement your research with openrice.com pictures and wade through reviews of others (usually with a grain of salt since a lot of them aren't really chowhounds). Sushi Mori in Causeway Bay is still a local favorite, but unfortunately Mori-san is nowhere to be found these days...no idea where he is. Kishoku is another local favorite, although the head chef is HK Cantonese (trained under the head chef of Ta-Ke).
Tomoe in Tsim Sa Tsui might be a good one.
You can also get a hybrid kaiseki/kappo with sushi in your meal at places like Kado in Central (chef is a local Cantonese speaker, who trained under Sase-san of Sushi Sase, and the food looks pretty respectable). Sushi Sase in Central may be another good one, although I am not clear on the prices these days, openrice and blogs may have more updated info. Sit in front of Sase san, and request that for your reservation.
I would recommend Hikari in Causeway Bay, strictly a kappo ryori kind of place with a sushi course...last month they still had Hokkaido hairy crab/kegani (whole), Bluefin tuna head (kabutoyaki), and A4 wagyu, as well as torafugu (blowfish/farmed). Omakase starts at $800 but if you do $1200 (which I did) you can get some better goodies. Numata-san is the head chef and does a great job, and his osechi ryori mini set I had new year's eve was spectacular. The caveat is that there is always that mandatory 10% service charge on top of your bill.
My meal at ' Sushi Fuku-Suke ' on Hennessy Road, Causeway Bay was quite enjoyable. If my recollection is correct, they offer a few Omakase menus composing of sashimi, sushi and hot dishes at dinner time. Price range is around $1000 pp.
Chef is Japanese from Ginza, Tokyo, I believe?!
