If you like traditional clubbing Ragga might be the right place for you. But you'll have to wait some time before you get in and also deal with annoying bouncers, but once you get in you'll be amazed with great pop/rock music and a great atmosphere to party all night long.
It's an expensive place, be prepared to pay around $20 just to get in and inside you'll have to buy a bottle just to get a table, the bottle will cost you around $100 and the waiter will usually ask for a 20% tip, so don't be surprised. You can expect to find some of the most known Mexican celebrities and people from 22 to 30 years old.
Remember, if you want to get in you'll have to go well dressed: no shorts, snickers or t-shirts.
