Pacífico Restaurant Gourmet
Sure, you'll find well-prepared seafood and comida norteña at this Lambayeque mainstay. But even better are the hard-to-find specialties, including langostinos en salsa de ocopa (shrimp in a green sauce native to Arequipa) and causa de mero (grouper in a mashed-potato casserole). Chill digs and an easygoing waitstaff make this an ideal spot to recover from a morning of information overload at the archaeological museums just two blocks away.
