I forgot to touch upon this point. The Asian cuisine places will of course have dishes with these ingredients, although I will caution you on the overall level of Asian cuisine in Buenos Aires. Many of the fusion restaurants have incorporated these materials into their menu, although they will not always be available.

There are of course vegetarian restaurants that will cater to your exact needs, unfortunately, Im just about as die-hard carnivore as you can get so Im a lousy critic of these establishments.

Check out this link for a couple of places I could find after a quick internet search:
