For bottle service reservations, a minimum spend is the amount of money you need to spend on alcohol in order to reserve your table for free.
For example, if it says $1k min spend, you will need to spend $1000 on alcohol (usually two bottles) in order to get your table for free (before tax and tip is added).
The table is NOT a separate purchase.
Your final spend is determined by the amount of tax/tip/table fees added on to your minimum spend (which is 33% at Dragonfly); so the total “final” cost for $1k min spend will be $1330 total all in.
