Top 100 Penuin is mostly local directed therefore stuffs and goods there are at local prices which is cheaper than what you get at Nagoya Hill Mall .
if you have googled it then you can have an estimated guess on how big it is .
if you by chance visit there , it should take mostly about 1 hour to look around shops in there .
the Pasar Penuin , for your information , is best visited during the morning hours . 12pm onwards and you wouldn't get much already as most stalls start closing down or that all their goods have been bought already until the next morning when supplies come in again .
by far the best local wet market is Pasar Penuin . remember that at these wet market you have the advantage of bargaining .
