I think it'll cost you about USD17.00 fee to enter the place. I can say it was worth it because there'll be a tour, free rides on the horse carriage and a sketch show of some ppl shooting at the scene.
There are also shops that sells fox skins and souvenirs which are quite reasonable. I didn't manage to buy any since i don't feel comfortable buying skins with the animal's head attaching to it.
As for the shows, I love watching the can can. It was tremendously entertaining. Once the show was over, my friends and I manage to get some photos with the performers at the bar.
Well, this will be one of the places I would recommend one to go. It's fun, it's hot and it's worth it.
