Sweet Mercy, if I'd known places like this existed I would have been a better man...
I'm going to forego too much of a description and rather give a PRESCRIPTION for eating at Viva chicken. (Briefly, decor is Chipotle-eque and price is somewhere between cheap and moderate).
Here's what you need to do:
1. Don't eat lunch. You need to prepare your body for the experience. A light breakfast is appropriate but you must cleanse yourself before the transformational experience that is Viva Chicken.
2. Order the Arroz Chaufa with pulled chicken. Order a side of fries. Order a soda. Close your mouth and step away from the counter, lest you alter from this path to glory.
3. While waiting for your order collect some of each of their sauces, your fries will serve as little more than a delivery method for these delicious spicy ambrosias.
4. Upon the arrival of your food turn off your cell phone, breathe deep and consume the deliciousness until sleep or exhaustion overtakes you.
Good luck traveler. The journey you embark on shall change you to your very soul...
