Though the food is rather simple, there are plenty of other reasons to make a stop at L’Eau Vive. An order of French Carmelite nuns runs the restaurant and donates the proceeds to charity. The location, inside an 18th-century palace across the street from one of Lima’s most important mansions, is quite convenient if you are sightseeing around the Plaza Mayor. Lunchtime visitors get a basic set menu with Peruvian-inflected French dishes that change often. Dinners feature elegant international courses like prawn bisque or trout baked in cognac. The sisters happily serve wine with the meals. A free show comes around 9pm, when the nuns sing a moving rendition of “Ave Maria.”
