We know the drill: Resort signs Broadway production to shack up in its showroom, performs needless surgery to maximize casino patronage. The Smith Center, however, is a real performing arts facility that respects the vision of musicals’ creators, and its audiences have enjoyed pretty much the same exact version of faves like Wicked, Once and Billy Elliot. One shudders at the thought of a single joke being snipped from The Book of Mormon. 361 Symphony Park Ave., 702-749-2012.
