Review: I travel to Buenos Aires frequently with work. My expectations of great vegetarian food are lower in Argentina than in most other places, given it's status as the Carne Capital of the World. I have been to Sattva twice and I have to say that it is consistent -- the bad service tends to negate whatever good karma the food might provide. I have been served by the same waiter both visits (several months apart). He has the world's worst personality -- you start to feel like you're not actually there. He makes it clear that he is not really interested in you or in serving you. I gave this place the benefit of the doubt last time but this time I say, "never again!" I think I'd almost rather eat meat than put myself through another meal at this place.
