You might find many of the reviews for this place under the name Ovejitas. That's the name of the chocolatier that shares the same premises at Acuarela the icecream maker. The Airbnb host made mention of an icecream place that is also a chocolate place and The Rough Guide also mentioned it as the best icecream in town. On the final night walking the 30mins from La Tablita back to the accommodation, I was glad to see it still open around 9pm.
I had two missions - the try the calafate berry and the chocolate. I had read about both and it seemed fitting to have calafate in El Calafate (given the berry was not in season in November) and the chocolate is called Chocolate Patagonico which means they are proud of it too. Both were exceptional - the chocolate was dark, rich and not too sweet whilst the calafate was tangy, sweeter with that distinct berry flavour similar to a blueberry with a little extra tart of a blackberry. The textures were thick and creamy and no crystals detected.
Although expensive, they really pack the scoops including stuffing the cone right to the end.
A local gem and one to add to the collection.
