I was surprised to see several reviews for this place, which is not really near the two main tourist areas (Miraflores and the historic center of Lima). So I had to check it out.
This place puts its menu of the day on their Facebook page daily, so I waited for something that sounded good and went. They recommend that you call before noon and tell them you're coming and what you want that day so they'll make sure to save it for you. However, if you show up at opening time or not long afterwards, you'll probably get what you want.
As of November 2014, the meal of the day is 11 soles (about what you pay in Miraflores). The mixed organic salad was very good, and a beautiful presentation. The main plate for me was quinoa tossed with roasted veggies, which was also good. The meal comes with mate to drink. I also had the apple crisp for dessert for 5 soles. It wasn't overly sweet, and the topping wasn't really crisp, but it was good. They also had vegan brownies, which I might try next time.
Overall a very good experience and I look forward to going back. The only negative for me was that there wasn't a lot of protein on the plate, apart from the quinoa, which has protein. Perhaps a little ramekin of beans would have been nice, but still a great meal at a good price, in a pleasant setting.
As others have mentioned, the restaurant is situated in the courtyard-parking area of a residence. If the door isn't ajar, just ring the bell and they will open the door.
Cons: Getting there a bit complicated
