Casco Viejo (the old city) is currently undergoing a massive revitalization. Everywhere you look new construction and remodeling is underway. Already a major attraction of Panama City, this charming, colonial location will soon be able to host even more hotels, restaurants, and bars. As I strolled around Castro, I was reminded of Havana, Cuba. Indeed, the city consists of Spanish Colonial architecture, and was designated a UNESCO World Heritage Site in 1997. Being that I love rooftop bars, I was more than delighted to stumble on Tantalo, a new, modern bar and restaurant with great views of Panama city. Get there early, at sunset the place is packed!
