I am puzzled why the employers are looking at your CGPA instead of your experience? You're already 34, I would assume a good 10 years experience in the field? or they purposely nip pick this since you have no advancement from your past career?

My advise is stick to your current job. find in SG a similar field then hop. trust me, F&B is not as rosy as it seems. its very tiring. working long hours and you cannot sit. Job is pretty much repetitive. most of the people working in this field got attitude. I can't blame them as its a repetitive job. imagine for 10 years you will be working the same job everyday without any new challenges. quite boring.
