Sushi and other fare in the land of the beef

Most people identify Argentinean cuisine with beef, and to be sure there is a lot of it about, but when visiting say, Buenos Aires, you will find a varied culinary offer. A few restaurants and cafes that I have visited in the past:

In the hip district of Palermo Hollywood
Dashi. Japanese cuisine. Eating and learning how to make it.

In the traditional  district of Recoleta
Café Victoria. A pleasant cafe close to the Recoleta Cemetery and Buenos Aires Design.
Café La Biela. Opened in 1850 and an institution in Buenos Aires. The writers Jorge Luis Borges and Ernesto Sabato were regulars, as was the famous racing car driver Juan Manuel Fangio. Great cakes.

Sorrento. The branch in Posadas offers Italian cuisine in elegant surroundings.
La Rambla. A small neighborhood cafe. The beef sandwich is recommended. (Posadas 1602, in the corner with Ayacucho).
In the modern district of Puerto Madero
Itamae Sushi. Lunch "al fresco" with views of the river. In Olga Cossenttini 1553.
La Cabaña. Beef, beef and more beef.
Café Amma. Nice modern cafe with papers, magazines and free wi-fi. (Juana Manso 1626).

Bon appétit!!!!
