El Gran Inka is a Peruvian restaurant in Key Biscayne perfect for a family lunch after a morning at the beach. Everyone could order their own big bowl of ceviche or lomo saltado, though you’ll get the most out of this place by sharing everything (so brace your dad ahead of time). The wine bottles hanging on the walls and Restoration Hardware-esque chairs make this place look fancier than it is. But it’s walk-in friendly and you can show up in Havaianas without a problem.
