They have an awesome happy hour, with refreshing margaritas and some appetizers. Their tamarind margarita is tart and thirst-quenching, so make sure to try that on your next visit. I can tell you that their regular menu is pricey, but their dishes are large enough to share (2 ppl), and they are very tasty.
Perhaps the best part about Viva Mercados is their staff. They are always happy, super friendly, and always willing to go the extra mile for you. Have a taste of a margarita? Sure!, keep your drinks and chips filled to brim? Absolutely.
Come visit this restaurant and buen provecho!
