The Rio Theater is a live performance theater built about 2000 in the old Rio Hotel.  The theater was originally intended for the Helper Intermountain Theater (HIT) Company, but the founders of that non-profit organization moved out of state before the Rio Theater was completed. 

The Rio Hotel was originally owned by George Londaris. In 1935, the California Hotel occupied the upper floor, with the Greek Zappion Coffee House on the main floor. ^[1]
