MCA Market is the most famous shopping center in Puerto Princesa for souvenirs. They have the most complete items from shirts down to the key chains and ref magnets. This was our last stop during our City Tour and we managed to spend the last money we got to buy some goods to bring home.
I would suggest that you go here not on peak hours as the number of people tend to increase crazily during these times. The lines could take forever so bring a lot of patiences with you.
