been there before, dont know who invited me back then. it was 2 years back if im not mistaken.

dinner buffet is only nasi goreng + other side dishes.
health assessment, they take ur weight, BP & other standard health check & advise u accordingly.
1 night stay - previously i got the free spa or sumting, but didnt take up the offer, since validity is like 1 month after u attend the preview.

in short, they are asking u to sign up their membership program which costs onwards of 10k. if u have money, then just go ahead.

no offense if got golden horses people reading this. but it is priced high, where most people cant afford.
