I never go to PV without going to Zoo Bar. It is a must if you want to drink and dance to loud music, just a fun time with hot music. They have a cage you can dance in and drinks are 2x1 -very fun!

There is another club called Hilo a few doors down from the Zoo on the malecon. Also very fun and larger than the Zoo, a slightly more upscale and still really fun. Drinks are pretty cheap here too.
Nikki Beach is a very sexy and gorgeous club. It's on the beach with big beds and pillows, a little pricier than most spots but right in the marina at the Westin. IMO the setting is amazing.NIKKI BEACH
The No Name Cafe is a great sports bar to start with but like Dougsgirl says I don't think they have dancing.
Also google Christine's, De Santos, Collage. Have fun!
