El Gran Inka dishes out the rich flavors of Lima with a menu full of authentic Peruvian cuisine. A spacious, modern dining room is an idealistically elegant-yet-casual date setting, and a shaded outdoor area provides a calming backdrop for contemplating archaeological oddities and analyzing text-message meanings. The restaurant's mixed-seafood ceviche is served cold with calamari, shrimp, mussels, and octopus alongside glazed sweet potatoes and Peruvian choclo corn ($14.95). For some South American heat, try the sizzling shrimp-and-calamari skillet, boasting flavor injections of garlic, onion, and red bell peppers, served with golden potatoes ($14.95).
