Incredible value, brilliant tour - David was an excellent guide, taking me to places I never would have been confident enough to try otherwise. I wasn't sure if I would be able to do the tour as a solo traveller, but David arranged to collect me from my guesthouse and took me to nearby market food stalls for food and drinks. Along the way, he also shared some local knowledge and stories, and pointed out other places and food items that were worth trying. The tour is unbeatable value for money, especially since the tour will save you money afterwards, by giving you the confidence and knowledge of some of the best street food to eat in the city. This tour was one of the most memorable parts of my trip to Mexico, I only wish I had done it sooner!
