Asking for a friend...
No, in all seriousness. We are having a full open bar based on consumption. I expect to pay about $4,000 with gratuity considering it's premium liquors and we're in MA where everything is expensive.
I do think cash bars are tacky, but if you couldn't afford to have one, what would you do instead? Not have a wedding?
Not looking for why cash bars are tacky, but for suggestions of alternatives. If you couldn't budget for it and didn't have other extravagant items for your wedding.
