I am happy to tell you that the Food Business Regulation (Cap. 132X) was amended to allow more flexibility to operators.  With the amendments taking effect on 1 August 2010, the food room requirements including the minimum area of kitchen and food preparation room for licensed general restaurants, light refreshment restaurants and factory canteens are relaxed.   For enquiries, please do not hesitate to call your licence officer or my office at 2397 2688.  You can also find the revised food room requirements in the LegCo paper: http://www.legco.gov.hk/yr08-09/english/panels/fseh/papers/fe0609cb2-1755-7-e.pdf.
