From $20 to $30
When we were there in May, each drink we had was $25. Also, be aware that they don't have a fully stocked bar as they didn't have all the stuff needed to make something as simple as a Moscow mule or white Russian.
$15 -$20 a drink for liquor on average from my experience, there well is all premium. Beers are the cheapest thing at $10 when we were there in December, 2018. Best thing to do is get a promotor to get you bottle service. It's about the same price per drink and comes with seats. Xclusive Vegas VIP is who I book through for clubs or shows. Best service and prices ever.
