I've had pretty good dishes here. The flavors are varied and unique, and the fare is light and healthy. They offer a good variety of vegetarian options and lunch specials.
I wish they didn't close so early. The atmosphere is also a little weird - its kind of like dining in a knitted-clothing store. Once you get past all of that, its a nice experience. Authentic? Who knows. I've yet to go to Peru. In the meantime, I'll keep enjoying the food they serve here.
