Halloween, in the U.S. style, with pumpkins and costumes, is becoming more popular here in Lima. In contrast, November 1, Day of the Dead, is an old tradition, and a holiday. Unlike in Mexico, Day of the Dead is not a massive face-painted celebration, but rather, a more reflective time to visit family in the cemetery (although, still with food, drink, and music, I’m told). The idea of trick or treating is also a new idea and is beginning to happen in some places. Certainly, the stores would like it to take hold. They have already started selling Christmas items.
A few years, I was in El Pan de la Chola on Halloween, and the staff were painted in Day of the Dead makeup, adding a festive touch?
As strange as it seems from May to September, there is no sunshine in Lima. If you imagine an overcast day that lasts for five months, then you are getting close to imagining it. Therefore, it is necessary to get out and find some direct sunlight. One of the places is Paracas, three or so islands to the south of Lima. Go for a weekend. There is a national park and sunlight. Maybe. If you really want to make sure, go down to Ica, location of the Nazca lines. Make sure to stop at the pitstop at 
We went for a weekend. Paracas is a small town that seems to exist nowadays for the tourism related to the Paracas National Reserve, a vast sandy national park, and the Ballestas Islands which is part of the park but a separate boat tour. These islands were the source of guano, bird poo, which is used for many products, including fertilizer. It was a big industry. The birds still produce and they like to aim for the tourists (wear a hat and long sleeves). You will also see sea lions sunbathing. The boat ride is two hours with no toilet, no roof, and lots of wind and water. Be prepared.
As much as I enjoyed the boat ride and watching the local fauna (a man and his 12 offspring) on the boat, I actually preferred driving around the desert part of the reserve and finding well appointed viewing platforms and amenities along the way.
As I did 
That said, I start with including photos of a “criollo” or “creole” soup of meat, noodles, and fried egg (can be had in lots of restaurants. The addition of a fried egg to a dish tends to make it “criollo”). Plus an uber modern dish of sushi made with raw tuna and foie gras (from Osaka restaurant). The photo doesn’t do it justice. You will just have to go there and try it. You may feel the earth move.
