Rotisserie chicken Peruvian style is one of my favorites, and viva does not disappoint. The chicken is well-seasoned with herbs and their sauces are decent. I always get the fried yucca as a side and sometimes their plantains (maduros/sweet and ripe fried plantains).
The price point is great. It is a quick-service restaurant - so you go to the counter and order and they bring out your food. Their covered patio is nice, but finding a table at lunch is sometimes difficult.
