I just arrived back in US from Peru, had a 1 day tour from Lima Cabs. Also deserves high recommendation. We hit the ruins in Miraflores, lunch, and then did the historic tour of downtown followed by dinner at Museo Larco. All was great. Can recommend Museo Larco for both content and the restaurant there is fantastic. Found the driver/guide from Lima Cabs to be extremely knowledgable and helpful. Prices were quite reasonable for an hourly rate, but they also have pre-designed itineraries as well.
