When visiting Mendoza you will probably see ads for Alfajores "Entre Dos" which seems to be the latest rage. I will not explain what an alfajor is, but these recently launched variety are quite good.
I went to check out the place where they make and sell these treats. Located at the Lujan de cuyo beach around an hour from the city, it can be accessed by car or inter urban bus.
at the spot you can buy all sorts of sweet treats like dulce de leche,chocolates and of course their premium alfajores with fillings that include Cognac and whisky as well as the orange-dark chocolate one.
The location is also worth while visiting cuz just across the road sits the river and beach with a great scenery.
