Yes, we know of a couple of options.
In addition to its famous mud wrestling and mechanical-bull riding, Gilley’s, located inside the New Frontier on the Strip, has line dancing Thursday through Sunday from 8:30 pm, with free dance lessons from 4-6 pm on Sundays. Admission is free before 9 pm with a $10 cover charge thereafter and the venue stays open as long as the crowds remain — typically until 2-3 am during the week and 4 or 5 am on the weekend.
Dylan’s Dance Hall Saloon, located at 4660 Boulder Hwy. between Boulder Station and Sam’s Town casinos, is another favored honky-tonk hangout that has line dancing every Friday and Saturday night from 7 pm "until the cows come home," and offers free dance lessons from 7:30-9 pm both nights. There’s no cover charge. Call 702/451-4006 for more information.
