We were happy to find this place in Iguazu as there are not many vegan options in town at all! This is a great place for vegetarians and the best selection in town for vegans. We ate here in Feb 2015 and had the all you can eat evening buffet. It is somewhat pricey for a backpackers budget at 230 pesos per person but we negotiated a discount to 175ps with the manager when we went in to see if there were many vegan options available at around 5pm when they were laying the buffet out. There are lots of salad items, roasted vegetables, rice dishes and a nice pumpkin and walnut dish. There is a good fruit platter for dessert. There are loads more vegetarian dishes too.
Cons: Not cheap
