The package the we got with our wedding venue for 100 guests currently includes wine service with dinner (1 1/2 pours), and a champagne toast. We are also going to add on 2 signature cocktails. Each one is a 3 gallon dispenser and serves 92 drinks. So this comes out to 184 drinks in total for the cocktails. We may add on a third dispenser if we get low since these are a lot less expensive than hosting a bar ($3 a drink vs. $10 a drink).
Since we will probably have enough alcohol with just these options, should we not even offer a cash bar? I have heard that they are perceived as tacky so maybe it would be better to just leave it out. As a side note, the cash bar has a $500 minimum or a $150 bartender fee will be charged.
Also, anyone have recommendations for signature cocktails that most people like? My Fiance and I are fans of tequila and rum. Our friends are happy with any type of drink and my family members like margaritas.
