Slush Shack will be on-site from 4 p.m. to 9 p.m. serving slushies in four flavors, alongside fried tacos filled with beef or chicken, loaded nachos and walking tacos. Beyond special events, Slush Shack offers promotions such as Snack It Forward, which allows customers to purchase a meal, snack or slushy for someone in the community as a random act of kindness. For now, Slush Shack remains in its soft opening phase, operating abbreviated hours Tuesday through Saturday while settling into its new routine. In addition to its current menu of fried tacos, walking tacos and nachos, Slush Shack may eventually add pizza slices, Polish sausage, salad flights and regular or sweet baked potatoes topped with chopped bacon, chives, sour cream and melted cheese.
