Fusiones is located inside of a small shopping mall just off a busy street corner on Av. El Sol, about a block from the main plaza. You don't really notice this place as you walk by, as there is just a small sign inside a doorway. It's upstairs at the mall, so you walk up the stairs inside to reach it.
Inside, it's Asian-styled (indeed, the place was full of Japanese tourists), with red and black accents and dark wood tables. The menu is called "Fusion" because it takes Peruvian dishes you see all over and mixes them with spicy chiles and asian style sauces. The result I must say was impressive. Prices are moderate, about 15 PEN ($5) for an appetizer and 25 PEN ($8) for a main course. Menus are in both English and Spanish.
We ordered a couple dishes which sounded just ok (spring rolls and stuffed chili peppers), but both turned out to be outstanding. These are unlike any spring rolls I've ever seen, and gigantic. The chili peppers were stuffed with meat and veggies and were delicious especially with a spicy sauce they brought on the side. The Aji de Gallina was definitely the best we've had in Peru so far, even tastier than we had at the Orient Express hotel. Nothing fancy, just use of spices and sauces that makes things really yummy.
We had a delightful surprise with Fusiones, very happy we stopped by.
