Although it's very hard to find meat-free food in Asuncion, I would not recommend this restaurant. It left me wondering why they even call themselves vegetarian. The price was quite high, some 45,000PYG a kilo. The food was also cold even though I arrived at noon, room temperature, like it had been sitting out for hours. This normally isn't a problem for me, but the food actually seemed old and unacceptable for the high price.
The food was a solid three-star experience, though it was nearly impossible to tell what had meat in it and a good +50% wasn't vegetarian--a bit misleading, it seems to me since they call themselves a vegetarian restaurant.
Seuel, right off the main plaza is far better, slightly cheaper, more vegan and vegetarian options, much nicer restaurant, and with free wifi.
Cons: Expensive, Lots of meat, Old, cold food
