I walked into a Taco Bell in the USA once, towards the border of Mexico. But I couldn’t convince myself to order ‘fast food’. Happily there was an actual Mexican cafe nearby where I had a decent Quesadilla. Once I crossed over into Tijuana, a local directed me to a Taco stall popular with the locals. The locals were somewhat surprised to see us there. Some people literally staring from across the road. But the people eating there and the vendors were more than helpful. Tasty, cheap and filling. Could only eat two. Perhaps 15 pesos each. Don’t remember exactly. So didn’t get to try a Taco Bell.
