Birthday parties with frozen drinks on tap

Birthdays are our most booked party. One machine pours two flavors, so adults get margaritas and kids get slushies from the same table, and nobody has to play bartender.

Two-flavor margarita machine set up for a party with balloons

Why it works for birthdays

  • Margaritas in one bowl, a kid-friendly slushie in the other
  • Frozen and ready before guests arrive, about 2 hours after setup
  • One machine serves up to 100 guests
  • We pick it up and clean it
★★★★★
We recently used River City Frozen Beverages to celebrate my husbands 70th birthday. We had guests between 5 and 85 so the margarita/slushie machine was a perfect fit! The set up was simple and care free - no fuss which allowed us to enjoy time with our guests while they served themselves. Steve was a delight to work with and made the process a breeze. I highly recommend River City for any event, large or small. Truly a good time and a tasty treat!
