I opened a Mexican Restaurant in December 2019 and we specialize in Margaritas in several diffrent flavors. This slushy machine is perfect!! We received great reviews on our frozen Margaritas, thanks to the Happy buy slushy machine! I ordered the 3 tank slushy machine , which holds about 3 gallons per tank. I use two tanks to make frozen margaritas and the other one we keep cold, to make margaritas on the rocks.
