Try Kin's Kitchen in Wanchai or Pang's in Happy Valley, both good Cantonese food and/but more low key than The Chairman. I went to Kin's last week and while it's not as amazing as it was, it's still pretty good (smoke soy sauce chicken is a signature there that's still a decent choice). The Chairman isn't as hard to book now if you try to book weekend lunch, I heard.
