I don’t want to go to a host club!

I’m going to Japan soon and my friends want to go to a host club. I am very against it because I have horrible conversations skill when it comes to guys and I don’t want to drink any alcohol because I’m a lightweight but if I were to go I would definitely not want to be sober. My friends are saying I should go just to experience it, but I don’t want to experience something I’m already uncomfortable with. I want to go to an Internet cafe and read manga, but they still want me to come instead.
Anyone been to a host club and not enjoyed it, knows what a first time customer goes through/pays, or any ideas how to convince them to let me stay at the Internet cafe while they go?
