The type of signature drink that you serve is solely up to you and what type of liquor you want as a base. We do like to tell clients that a good rule to go by is having a signature drink that is not too many steps. The reasoning for this is so that the guests can get served in a timely manner without having to wait in a long line. The more steps to a drink, the longer it takes to make it. We like to follow the preparation times below for how long it takes to serve the clients.
  • Bottled or Canned Beer / 8- 10 second serving time
  • Wine / 15 – 20 second serving time
  • Draft Beer / 20 – 25 second serving time (could be more depending on setup and location of kegs).
  • 2-Step Mixed Drink / 20+ seconds
  • 3-Step Mixed Drink / 25 – 30+ seconds
  • Mixed drinks with muddling – 35+ seconds
Please note, these are just typical base times. Our bartenders do get multiple drinks at once to lessen guest wait times and so that multiple drinks can be made at once.
  • Garnish for beer or mixed drinks
  • Bar ice to chill the beer and wine
  • Water bottles for after the caterer leaves.
  • Salt or sugar for rimming specific drinks
  • Napkins
  • Straws
  • Drink sign – though not needed, this does help when signature drinks are served
