Wow. You get a lot of bang for your buck on this one. Tadeo was great. You feel safe, there was a lot of info about the origins of Tijuana, we got taco lunch with drinks, we got a margarita, and tequila tasting!!!! There was a lot of info about different streets, which were beautiful and fun to see. We were also lucky enough to be able to check out a museum of the origins of Tijuana :)
Highly recommend for tourists AND locals who have never been to Tijuana! I've lived in Carlsbad for 12 years and really learned a lot on this trip.
