I am going to Lima for a couple days for work and will have a little downtime. Would love some recs on good food!

I just talked to my husband and niece who have both had a lot of good meals in Lima. They said you basically can't go wrong but here are some concrete suggestions:
For seafood and ceviche -Punto Azul OR Los Pescadores Capitales
for sushi - Osake
for typical Peruvian food Jose Antonio
for good views Embarcadero 41
They also suggest visiting an area called Barranco for shopping, music and food.
Have fun.

You might query Carlos Olaechea, a Food52 contributor who has mentioned in the past that he has parents from Peru: https://food52.com/users/1277588-carlos-c-olaechea. He might have some insights into the food scene in Lima.
