Thanks @coldsteem , I am reliving my experiences through your blogs :)
I ate at hearts twice. What amazed me there, was their juices. Almost a meal in themselves, I haven't had a fruit juice quite like it anywhere in the world :) I hear you re: Machu Pichu ^^ in addition to the extortionist prices there for food, is the lines and thus wait, to get anything. I likewise planned ahead, and bought lunch to go at Aguas Calientes.
Peace.
