In ANY club, your chances to fuck depend on your looks (body as well as outfit), behavior and wit. You'll have best chances in clubs that fit your style. So without any additional information, it's kinda hard to help.
In my experience, it’s a combination of luck, timing, situation, a bit of wit/charm and how you present yourself. Always — ALWAYS — start at the bar to chat up any prospective partners. This will increase your odds of success by a thousand percent. Stay humble, stay friendly and always be open to new developments. Best wishes!
