I was near Albufeira but had no patience for the usual restaurant for tourists (near the beaches). So I drove for a few quilometers... and found this gem, actually a place were local workers go to lunch at a reasonable price.
Eated grilled sardines (€4,50), salad (lettuce, tomatoes, onions and "pimemtos"), bread, 3 glasses of beer and a expresso. Total amount of €8,30, almost unbealivable!!!
