Don’t know what you’re into, but the strip clubs are kinda young crowded loud and play weird techno mashup. Last time I went you had to “buy” bottle service. So I wound up sitting in a place to loud to talk, too crowded to dance and too expensive to walk out of with music I didn’t understand.
Plenty of post on here asking for clubs with “older” crowds. My favorites, all no cover, were (its been a few years, you should call)
The Blue Martini in Town Sqaure, Thursday night was Salsa Night, it was great, my favorite.
The Bourbon Lounge had an eighties theme, great dance floor, lots of room, DJ was entertaining, they played songs I knew, off nights were best, Friday and Saturday had several drunk 20 somethings.
Gold Diggers at the Golden Nugget on Fremont. It’s a little low rent compared to the strip, but it’s clean and has a great dance floor and Fremont is a blast. Beware though, I’d go “with” a date. The place seemed to be a gay bar, I got hit on when my date went to the bathroom, but the place was fun, and you’ll never get judged in a gay bar for having a date 20 years younger, 6 inches taller and obviously out of your league.
