We have travelled to Foz for the lat 2 years and each time we have visited Cais several times during our stay. The location of Cais is ideal, sitting on the beach right on the edge of the stunning lagoon and is an excellent spot to enjoy the view or watch the sunset. The location is also ideal if you have childres as there is a clear view of the beah from the seating outside. I must make mention they serve excellent cocktails - you must try the strawberry margaritas as they are addictive. The food id also of excellent qualiity and the service always comes with a smile. I look forward to my next trip to Foz.
