I really don't know where to start with this place. Everything is good. EV-ERY-THING. I find the best value with the Tacu Bowl w/ Chicken; it's so much food for less that $9. Every layer is always perfect from the rice & beans to the onion/tomato salsa to the shredded rotisserie chicken. Don't forget to order extra Aji Amarillo sauce because you'll need it. This is quite possibly the best "sauce" I've ever encountered. I swipe my finger to pick up the remains every time, so that says it all.
As far as the sides are concerned, nothing is short of excellent. I've had fried yuca many times before including South Florida (and one anonymous place down Central Ave here in CLT), but Viva consistently delivers the best I've ever had. Crispy on the outside, creamy on the inside. Dip that bad boy in the Aji sauce and you're in business. The fried plantains are also clutch. I haven't ventured toward much else, but why would I? I'm here for the Peruvian food.
Viva has a great product and they're booming. They've got healthy, delicious food that you order at the counter. Don't forget to wash it down with one of the eclectic Hispanic beverages, Cheerwine on tap, or local beers!
