Chicken piri piri is super popular in the Algarve. It's basically a whole grilled chicken cut up into smallish bite size pieces. It's spicy and juicy and really good. Usually comes with fries and a tomato and onion salad.
Well they say the original place that started it all is in Guia Algarve and the restaurant is Ramirez. It's always busy and the food is good and hot, prices are very reasonable. A whole chicken with fries is €13 tomato salad is €2 and the house wine is €5 - not bad. Remember the nice basket of bread, the olives, sardine pate and cheese is not a gift it costs money - they call it a "covert" which usually runs you about €2.5 a person if you eat all of the above.
Guia is located just south of the N125 and is about 6 km north west of Albufeira.
