San Martin, Peru
The Tree House RestaurantYou have to climb a few steps to reach this romantic restaurant, but it’s worth the effort, even after Machu Picchu. Beautifully presented dishes range from beef tenderloin to grilled trout with golden aguaymanto berries. The Tree House is also one of Aguas Calientes’s best places to try alpaca steak, yet vegetarians find tempting options, too, like ravioli with goat cheese and mushrooms. The tight dining room, nestled in the boughs, is romance-dreamy; be sure to reserve.
