A Fremont Street fixture since 1947, the Nugget has remained one of Downtown’s storied establishments. It’s the first Vegas resort Steve Wynn owned; he constructed its first three towers and roped in Frank Sinatra to appear in its commercials. It’s home to the world’s largest gold nugget, the world’s most exciting pool slide (through a shark aquarium) and a number of the city’s favorite restaurants. And it maintains an air of old-Vegas elegance to this day. 702-385-7111, goldennugget.com.
