I contacted Papa John's HQ about the outlets in Singapore (Tampines and Hillview), which seem to have gone off the radar.
Their reply:
"Dear Gabriel,
Thanks for contacting us. Unfortunately we have closed our 2 franchise stores in Singapore - March 31st. We appreciate your comments and please feel free to contact us at the number below if you need any further assistance.
Thanks again and have a great day!"
Oh well, at least I got to try it once (in Singapore) before it closed...
Good food in Singapore doesn't last (one way or the other)
