An easy 5 stars here as it's so good. Our waitress (whose name I missed) was really good and explained the menu - which needed fully explaining to us Brits. We didn't really know what we were ordering e.g. tuna pica-pau but WOW it was all so delicious including one of those 'best I've ever tasted' desserts called 'sericaia with fermented plum'. Just try it!
With a lovely Douro wine this was all at a reasonable price. Our waitress continued to be friendly and very helpful making this a wonderful last night in wonderful Porto.
