Frankly, there is very few to see. The Caminito is infested by tourists, and therefore by “tourist eaters”. You feel like being a walking purse most of the time. The place has lost most of its charm. Except to see a match in la Bombonera, which is really increible, I would not recommend to go there…
This is only a place you are supposed to go.
There are places much more authentic than this one in Buenos Aires
