Every meal there starts with a roasted corn snack served with a spicy green sauce.
When I'm there, I always get their delicious mixed seafood ceviche appetizer. You can adjust the spice level
as well (I always ask for spicy!) It's served with giant corn kernels, which is common in peruvian food, and goes really well with the spicy, tart sauce.
Lomo Saltado is a famous traditional Peruvian dish that uses beef strips, french fries, onions, drizzled with soy sauce and served on a sizzling platter! Tell me that does not sound awesome....whoever came up with this dish is genius! Oh! Calamares' version is great, trust me and just make sure you order it when you get there!
Another popular Peruvian dish is their rotisserie chicken, which is seasoned quite differently from what you might usually get. Their half chicken is tasty and even the white meat stays moist and juicy.
One time I was there and also ordered a stewed beef dish (I forgot the exact name), and it came with rice and beans (as well as a piece of steamed yucca). This dish was also delicious and I believe was only around $10.
