I haven't been to this place in a few months, but since there's only one review, I felt that I might as well give my two cents! This restaurant is part of the En (宴) group - http://en.com.hk/ - a group of restaurants that brings primarily Okinawan cuisine to our humble home. I've been here multiple times, bringing friends and family, so this review is an amalgamation of the good and bad of those few times.
The first noticeable thing upon entering is the dense smoke and noisy chatter of Japanese - always a good sign for a Japanese restaurant / izakaya. Although it boasts Okinawan far, they also have a some standard Japanese fare, with yakitori, hot pot, and noodles (soba / udon). However, if you come here, I recommend trying some things that are not on the menu of typical Japanese restaurants.
I haven't been here in a while, and cannot remember the Japanese name of the dishes. I've outlined the main ingredient of each dish. But they have English names on the menu, so it should not be a problem.
A few memorable dishes are the stir fried carrots and pork (にんじん焼き), and the stewed pork (らふて). The pork is tender with a sweet / savoury combination that balances nicely, and resembles some Chinese dishes. The stir-fry is a great combination for beer lovers, and feels healthy.
On different occasions, we've tried some noodles, yakitori, even sushi. But the only dish I whole-heartedly recommend - and everyone I've brought here absolutely loves it - is the tuna jaw (まぐろのあご) . It isn't on the regular menu (either on "seasonal specials" or completely off it), so make sure you ask them if they have it! It is grilled with salt and pepper, and aside from the ridiculously pricey belly (とろ), it is the juiciest party of the fish. Although pricey, it should be enough to fill two, and will leave you wanting more. I swear that last time we went, we ordered two portions because one simply was not enough.
Word of Warning: if you go to the restaurant late, or if it isn't in season, they might not have this delectable treat. Be careful if they suggest another fish, most of the time they'll charge a dear price, but it will be nowhere as good or filling as the tuna jaw.
This place is also a great place for Japanese drinks - they have an extensive list of beer (draft and bottled), sake, shochu, and most importantly Okinawan Awamori (泡盛).
The restaurant is a tad pricey, and definitely not for a regular night out. But keeping costs down by just ordering the basics - including the tuna jaw - and some drinks might turn it into a night to remember.
