Wow! Going to the zoo was definitely an experience I won't forget. If you want nightlife this is the place to go. The music is VERY LOUD. If it had been a little quieter I would have given it more stars. Do not go here if you want to do any talking or visiting with your group. The men in our group got patted down when they came in, although the women did not.
This is the place to go if you want loud music, lots of dancing, and cheap drinks. All the women in the group got coupons for two free margaritas. One guy ordered a beer (all drinks appeared to be 2 for 1) and got two beer in his own bucket complete with ice!
There are also girls who come around with tequila shots. You can't miss them as they blow their whistles louder than a traffic cop. They roam around (way too often) and will give 3 shots of tequila for about 35 pesos. They are kind enough to tilt your head back and pour them in your mouth for you. Being a bit of a germ phobe a was pleased to see they appeared to use a disposable plastic shot glass and each different customer seemed to get a clean one. The also offered "moppets", which I assumed was when they put your head into their chest, but that did seem to be an optional part of the shooters.
I won't go back, I am just a little too old for that. But if you are young and love to party you will probably have a great time.
