Halloween in Costa Rica

There’re many ads in internet about places that celebrate Halloween, those ads are guides that show you information about them.
I read an article about Costa Rican Halloween parties, it shows places in San Jose where you can go and celebrate Halloween, it also has information the from most expensive bar through the cheapest one.
When October 31st gets closer Costa Rican people find their costume and prepare to celebrate this foreign custom. People go out with a costume, dance and go party… But basically that’s all what we do in Halloween. In this country there’s no children asking for candies or doing “trick or treats”, people don’t decorate their houses, they just use this day to have fun.
