My finance and I booked a combination Alcatraz/ Craft Beer Tour through SF on Tap
and had an outstanding experience all the way around. The communication in advance was outstanding with clear instructions/pictures on where to go for both segments.
The Craft Beer Walking tour was a truly outstanding experience. Adam is highly knowledgeable about both the City of San Francisco and craft beer. We got to see an hear about the history of the Piers, Fisherman's Wharf, North Beach, etc. as we walked around the city. We even stopped into a historic pinball/gaming museum briefly that was really fund to see.
The best part of all is that it felt like a day out with new friends. In addition to us, we met Tomas and Joakim from Sweden and had great conversation over beer. The beer was excellent quality, but I really don't think you need to be a beer lover to fully enjoy this tour. There was also a significant amount of beer during the tour. We really talked about a variety of topics, learned about the city and had a great time. Adam was also very generous with his time as the tour ended up lasting longer than was advertised.This has got to be one of the best experiences in San Francisco and is a great value for the money.
