Will defo try the mexican place. Also saw one in godoy cruz near palermo station that is meant to be good.
Miranda is an awesome parrilla that's veggie friendly. They also brought out a couple of english menu's. Everyone had a great meal including the vegetarians; it was pretty perfect to be honest. defo recommend booking ahead as it was full the whole time we were there.
Bio is a quality veggie/vegan restaurant and I would happily go there again. They had a really creative menu.
BsAs Verde was good for lunch. It has a lot of raw stuff and fresh juices.
Kensho was more of a top end veggie restaurant but you get what you pay for, it was fantastic
Garden - it think is the name - it's opp. Catedral subte on Florida and I think it's really just a juice bar but we tried the lunch and it was pretty shocking. The only miss during the week
We also went to the Japanese Gardens restaurant and it was ok. Pretty expensive and they served up some salmon by accident for my veggie family but the meat was good.
All in all I would say Bio was the best veggie place for value for money but Kensho if you want something a bit special
