and yes a small shopping mall is available in PORTO SEGURO, but with, the passarella to alcool, a couple hundreds meters away sure is not a must do activity. anyway ( tip for girls...) you can see a dozen shops and take a cup of coffey.
when i was there it was here that i got the best deal changing currency. no need to go to a bank ( they offer less, anyway...! ).
a big camelot street you´ll be abble to buy almost everything.
even food and drinks are available i strongly recomend "capeta", sold mostly, on colorfull stands, like in the picture, along the "passarela do alcool".
side by side, along the "passarela", with camelot standigs selling a little bit of everything, there are these colorfull shops selling mostly t shirts, shorts and clothing items.i have here a travelogue in my porto seguro pg.
