Hi there. there are usually loads of jobs out here for the hospitality since HKG is full of F & B outlets. However, do not expect to get paid a lot - its the usual, long working hours and average pay. Depending on where you're from and years of experience - you might find yourself underpaid for what you're doing.
There is an agency here which specialises in hospitality recruitment - GSA or Glover Sey Associates if i don't remember wrongly. Google for them and you'll find their website.
Or search
www.scmp.com in the classifieds section for jobs.
best of luck!
