Make sure you’re hungry when you arrive at Oh! Calamares. The portions are huge. We barely put a dent in the mountain of arroz chaufa (Peruvian fried rice). Start with the Choritos a la Chalaca (New Zealand mussels topped with vinegar-marinated onions and Peruvian large-kernel corn) or any of the ceviches. There is a good version of fried yuca with Huancaina sauce. I had the Picante de Mariscos, a delicious bowl of shellfish in a yellow chili pepper cream sauce.
Oh! Calamares is a festive neighborhood spot with a full bar. Friendly service in both English and Spanish. We went with the kids on a Friday night around 7 pm without a reservation and got a table right away. By the time we left, there was a wait and some musicians were setting up for live music.
