Just got married here in Feb. Rented out an old mansion in Barranco, and the manager there pretty much doubled as a wedding planner - found the entertainment, food, decorations, etc., for no extra "planning" cost. Even made sure there was vegan food for myself and several guests.
The house is called Casa de Leeuw, and has a decent website including prep pics from our reception. (We did the civil ceremony there too.)
