There are a wide range of dishes in Peru, many are a mix of local foods and introduced cultures. For example, in and around Lima, you'll find a lot of Chinese influenced flavors. Mostly Peru has it's own unique array of meals like those you can find here http://incatrail.info/peruvian-food/ including Cerviche, a popular raw fish dish. Cuy Asado (roast guinea pig anyone?), or the delicious Aji de Gallina, a chicken dish.
If you are traveling with a tour company, you'll have you deals cooked for you, often by local chefs who will serve you a delicious variety of local dishes throughout your trip.
