Minivan to Hua Hin - where to catch the bus from exactly?

Hi,

I understand that we can take a mini van to Hua Hin from the Century Cinema near the Victory Monument. Does anyone know what road is the Century Cinema on? I tried to look for it on a Bangkok map but wasn%26#39;t able to find it. Also, how often does it leave and how much does it cost?

Many thanks!
