Yushoku on Connaught Rd. West ... $298 all you can eat beef, sushi, alaskan crab legs and shabu shabu. We ate all that and ordered more :D

HKD298, although if you skip the Alaskan crab and Japanese beef it drops down to 188 per head for unlimited grill, tempura, sushi & hot pot. Bargain. I've had sushi at other restaurants that was $298 a piece, it's really expensive for the good stuff in some places but I gotta draw the line (that kind of restaurant is not my choice by the way – the majority of your bill is going on rent). Here the fish quality is, I'd say, 80% but by the time you slap a pile of wasabi on it, super cool. Take 4-6 people and go nuts: GF, 145 Connaught Rd, Sheung Wan.
