Vasalissa
Callao 1940, Buenos Aires, Argentina
Also at 3 other locations in Buenos Aires

Vasalissa imports all of its chocolates straight from Belgium, so it has a much more European feel to it than the other chocolate brands, although for that feel it also charges at least three times as much. I paid higher prices for this chocolate [...]

Viejo Oso
La Pampa 2120, Belgrano, Buenos Aires, Argentina.
Also at: Montevideo 1594, Barrio Monk, Buenos Aires, Argentina

Overall, way better than most chocolate in Argentina, rivaled only by the likes of Mamushka. There are interesting, unique flavors, but not at the cost of chocolate quality. Truffles are outstanding especially—flavors aren’t big, but very well-made, with delicious ganache [...]

Abuela Goye
Mitre 258, Bariloche, Argentina
Also in Buenos Aires

Great milk chocolate and second only to Mamushka and Viejo Oso in that department. Milk chocolate is almost flawless, and I would almost exclusively buy milk chocolate from this store, since the other types of chocolate tend to be horrible. This isn’t so much of a problem, since [...]

Fenoglio
Artisanal Chocolate Producer/Chocolate Museum
Av Bustillo 1200, San Carlos de Bariloche, Argentina

Very good overall. Flavors, especially the creams and dulce de leche are just right. Good bittersweet chocolate pieces, and great use of nuts and swirls. The main flaw is in the sweetness. There is so much that it’s cloying. Also, the pure chocolates are bland.
Pieces I [...]

Bonifacio
Artisanal Chocolate Producer
Located at Mitre 171, Bariloche, Argentina

Good pieces with chunks/nuts in them, but horrible quality in general. The chocolate is overly sweet, to the point of being cloying, especially in the case of the milk chocolate. Only good for fruity/unique pieces.
Pieces I had:
Hits: Frutilla con yogur/strawberry with yogurt, cherry with dark chocolate [...]

Mamushka
Artisanal Chocolate Producer
Mitre 298, Bariloche, Argentina. Also found in Buenos Aires.
Mega Keeper!
Hands down, my favorite brand of chocolate in Argentina. It is so good that I would say it’s comparable to, if not better than, most all of the brands I tried in Europe, including the ones in Belgium. There are no misses at all. [...]
