The best organised food tour I ever been to, in any location. Andre, the guide, is very passionate about his city and knows all there's to know about it. The whole tour takes around 3/4 hours, always walking, and offers a little of everything. Coffee, sweets, meats, views and history of Porto and, of course, a fair share of wine. Highlight: the Flor dos Congregados family restaurant. A very old and hidden gem, the kind of place it would be difficult to discover on my own.
