Bottle service is the sale of liquor by the bottle, usually in lounges and nightclubs. The purchase of bottle service typically includes a reserved table for the patron's party and mixers of the patron's choice. Bottle service can include the service of a VIP host, who will ensure that patrons have sufficient mixers and will often make drinks using the patron’s liquor bottle and mixers. The purchase of bottle service sometimes results in cover charge being waived for the purchaser's party, and often allows patrons to bypass entrance lines. The tip is also often included in the price.
