Hands down this place has the best mojitos in Charlotte!!! This is the first restaurant that I've been to in this city that puts fresh fruit in their mojitos, I recommend the strawberry and mango ones.
The decor and overall atmosphere is really enjoyable, we went on a Friday night when they had live Cuban music. We were also told that later that night, they'd open up the dance floor for salsa night.
The service was very prompt initially, actually too prompt. I've always had a pet peeve around being given my entree less than 5 minutes after you brought my salad out. Other than that one slip up, the rest of the service that night was excellent.
The food was very fresh and tasty. I had the calamari, chicken Caesar salad and the Havana Pork. The calamari was very fresh and had a nice tangy dipping sauce on the side. I only had a couple bites of the chicken Caesar before my Havana Pork came out, so I can't really comment on the salad since I just had them trash that. The Havana pork was nicely seasoned and extremely tender. Based on the way the pork was cooked, I'd recommend their pork dishes to anyone.
Pricing is very reasonable, most entrees run between $7-16. If you're looking for good Cuban food, A Piece of Havana is a great place to go.
