Finding anything these days really comes down to doing the right type of research online. That is especially true for finding the right nightclubs in Prague to consider visiting. Many people feel like just anything will do, but especially those not familiar with the area need to do their research.
Certain clubs are going to have certain reputations in Prague, or really any city around the world. It just makes a lot of sense for a person to look into what type of vibe they should expect from a club. Going into a club and spending money without really knowing what type of person is going to be in there can actually be pretty risky for those people who might be on a budget.
If there is no access to search reviews online, there is always the option to ask locals. They usually can provide useful information.
