Standing on Duval street near Sloppy Joe's (the most famous bar in Key West) amongst hundreds of Spring Breakers, you will hear the hip-hop/dance beats pouring out of Rick's, just begging you to come in and dance. There's a short line to get in and show the bouncer your ID (21 & up only), pay your $5 and make your way up the steep flight of stairs almost directly to the dance floor. The dance floor is PACKED, but you are drawn to it... the music just makes you want to dance. Everyone there is drinking, having a good time, and just out to have fun! There's a bar on the opposite side of the dance floor, but be prepared to push/dance your way through a lot of sweaty bodies to get there! It's easier to turn left at the stairs and go outside...
Once outside, there are two more bars, and it's a little less noisy. There are still tons of people, but at least they can hear you when you say "Excuse me" to get by. The bartenders are nice, but sometimes it's a little hard to get their attention. I can't tell you much about the drinks... I drank mostly bottled beer, which was once dissappointingly lukewarm. Past the outside bars and people is a set of stairs which will take you down to Durty Harry's where there's a live band (mostly belting out 80s rock tunes) and some more people. There's two bathrooms down here, which are sometimes less crowded than the ones inside Rick's. Part of this uncovered outside area overlooks Duval, so if you are taking a breather out here, you can people watch on the street below.
Another place to overlook Duval is on the covered balcony back inside (near the dance floor). This is where you can quickly escape the dance floor if you are on that side and just need some air.
I think from 6 to 11 PM, you can pay $10 to get in for "all you can drink." We never did this, so I can't tell you if it's worth it. They also had the same deal till 1 AM at Club Epoch, down the street for $6, and we heard it was only cheap keg beer and the line was so long at the beer stand, that it wasn't worth it. I can only assume that Rick's had sort of the same deal.
We spent most of the night on the dance floor, dancing with the hundreds of sweaty guys on the wet, dirty floor (be careful not to slip and fall like my friend!). They played mostly current hip-hop (Wyclef, Nelly, Jagged Edge, Shaggy) and some dance-techno (Daft Punk, Zombie Nation, Sonique). We were very happy with most of the music and the people there.
