At Osio Theatre this summer, enjoy a refreshing, cold Lush Slush! What's a Lush Slush? It's an adult slushie, containing alcohol, that's created in-house here at Osio! Right now, we're kicking off the summer with Very Berry Vodka and Summer Sangria flavors. During the warm months, we invite you to come in, watch a movie, and cool off from a hot day. Those age 21 and over can enjoy a refreshing Lush Slush from our concessions stand.
