Every first Tuesday of the month, you can find a fun night out at the Hard Rock Cafe on the Strip. If you're one of those unfortunate souls like myself stuck in the 18-20 crowd, this is always a great place to get an almost-clubbing experience. Check out some of the best dance crews in Las Vegas, a hip hop scene, and a good time! The Hard Rock is normally packed by midnight, which I think says a lot in itself. Ticket lines are normally pretty long so get there early or purchase tickets in advance if you actually want to enjoy the most of your night. Don't forget your ID or else you're not getting anywhere. Like any venue, they will mark you with the X of the underage. Great place for the under 21 club!
