Big Elvis is the best Elvis impersonator in Las Vegas, and his show is the best free show! It also helped introduce us to Bill's Gamblin' Hall, which is a nice little saloon and casino. Big Elvis captures the original Elvis's voice and spirit perfectly. He doesn't move around much, but probably neither would the real Elvis at this stage of his life. I can only echo the advice that others on Yelp have given: Get there early, enjoy a few of the reasonably priced drinks and moderate table limits while you're waiting for Big Elvis, and settle in for some of the best free entertainment in the city. You'll probably pay good money to see some other Las Vegas shows that aren't nearly this entertaining.
