we understand you might have not enjoyed the experience but besides the tour is advertised as a City walking tour with visit to wine producers at the description it describes entirely what we're going to do. We specifically warn that this is a historical tour with a visit to a cellar and tasting at the end, not a mainly drinking tour.
We could have summarized and adapted the tour if you were the only ones, but there were other 7 participants that wanted the tour they booked, and everyone made amazing reviews in other platform from June 26th:
"David is a local expert who exudes pride for his city. He is full of energy and provides an excellent story of the history of Porto as well as its current day situation and future prospects. he is very knowledgeable about the local port wine making process and helped me learn how to interpret the various styles and vintages."
"Great tour. David's presentation of Portugal and the city of Porto was expansive and very interesting. His explanation of the Port Wine industry was equally interesting. We had great looks at some interesting parts of Porto. Highly recommend this tour with David."
"David is a very engaging and passionate guide. It was very special to be guided by a local and learn not only about the history but the social and political climate today. David had many fascinating facts about everything from tea to tempura, and the Portuguese connection. The walking tour down into the riverfront was excellent - a lot of stairs (down thankfully!) through a very old neighborhood, lots of photo opportunities. We finished with a port tasting and lesson on how port is made and what the different labels mean. It was educational and delicious! We thoroughly enjoyed the tour and would recommend it to anyone wanting to learn about the history not just of Porto but Portugal from a knowledgeable and friendly local."
Resuming, we totally understand you wanted something different, but it wasn't us that didn't knew to read the crowd, it was you booking a tour without reading the description and then expecting to be adapted to your expectations.
