Every VIP table has a minimum spend. Minimum spend means the amount you would have to spend on alcohol during your stay. If the minimum spend of a table is $1000 then you have to pay that amount at the door when entering the club.
This then guarantees a certain table in the club, with bigger and better tables requiring a higher minimum spend. However, the tables and cover charges themselves are totally free. The entire minimum spend is credited to the bottles you then order.
The minimum spend of a VIP table changes on a night to night basis according to the location of the table, holidays, days of the week, nature of live performances, big-name DJs, and number of people.
