Moving to HK; Salary - 55k

Got a job offer to move to HK with 55k (680k/yr) as base salary.

Moving from India, where I am living comfortably

Need some understanding on expenses:

Rent (single, will stay in a studio) Groceries (would splurge on getting good food) Utilities (electricity, mobile, internet etc) House help? (Is that a usual thing?) Going out (eating out/party 1-2 a week)

Any help would be appreciated. Need to make a decision in 10 days. TIA :)
