hi wedding9999,
Pudu raya is a bus terminal for KL.every express bus will stop there but the terminal is old ,dirty and hot.if can ,try not to go there cos have gangster roaming around asking for money.
the best is buy ticket ,go to the bus and wait in the bus.
if u realy want to save money,u can go to larkin bus terminal at JB.a lot express bus going to KL cost ard RM30.
