Oporto is also the name of a Portuguese Chicken fast food
chain in Sydney
The stores were founded by Antonio Cerqueira, who bought over his chicken cooking technique from the city of Porto when he emmigrated to Australia in the 1970s. The method, known as churrasco "involves cutting it open, flattening it out, marinating it and then grilling it over hot coals".
The original store was in Bondi, selling "Bondi's Famous Portuguese Style Grilled Chicken Burger". Oporto now has 14 locations throughout Sydney. There are 3 burgers available at Oporto restaurants: The "Norm" (grilled chicken burger), "Bondi" (Norm with sweet chilli sauce) and "O'tropo" (Norm with pineapple).
The author suggests the O'tropo.
