Larcomar
I guarantee you that if and when you visit Lima in the future, you will visit this swank mall at least once. Prior to my visit, I asked why in the world would I want to? A mall is a mall. True! But, in our case, we came here because of its restaurants. We dined here everyday visiting each and every Peruvian restaurant chain. It was posh but none of the places we visited cost a horrendous amount to eat in. In fact, for our lunches, we never paid more than US $20 each time.
There was also a supermarket here called WONG which we frequented to buy bottled water and some food from. It was also here where I bought two oil paintings from a Peruvian Handicraft store named QALA. Basically, the popular Peruvian eating places like the Sangucheria, the Beso Frances, China Wok, and more have branches here.
In short, it's nice place to come and rest in after a hard day's sightseeing in the city of Lima.
