This was a very enjoyable tour. Andrés on the San Diego side provided information on the procedures for joining the tour with Carlos on the Tijuana side. I would suggest adding the phrase “Meet in front of the McDonalds” on the San Diego side. Carlos gave a very informative and fun-facts tour of Tijuana. We visited iconic historical places in town, including markets, bars, and cathedral. A couple of common and unusual alcoholic tastings were included. We enjoyed a lunch at a hidden restaurant that was definitely not on any tourist list, but the food was outstanding and definitely worth a return visit. All in all, it was a wonderful way to spend some time in Tijuana with very knowledgeable advice from a Tijuana native like Carlos, a very personable guide.
