Inka has spectacular food-- each entree we tasted had great flavor. Lomo saltado, Tacu tacu, and the ceviche all tasted so good. What was most appreciated was how unique the dishes were. The sauce for the lomo saltado is really savory without overpowering the meat itself.
The ceviche was really tasty and unique for ceviche I thought, but for $13-18 it is a little pricey. If there is a complaint against Inka, it's definitely the higher prices-- but for excellent food, unique flavors, and an upscale environment I won't complain.
