Jimmys is, well, ... historic.
Same staff has been waiting on the tables for the last 30 years or more. It shows.
Good to try once.. just to say you've been there and done that.
Not sure if I would want to go there regularly.
I agree with Skyrunner on the quality of restaurants in LKF / Soho. Overpriced and really don't think they approach international standards.
One exception might be Azure, on the 28th floor of Hotel LKF (in Lan Kwai Fong - across from the Centrium). Spectactular views and very decent food. Not that overpriced by far.
