I've been to Cuba a couple of times, and found it enchanting. The people are friendly, the food and drink are top rate, and Ernest Hemingway fans will love it! There's a lot of history at the Nacional Hotel from the 1950's era. Frank Sinatra, Eva Gardner, Gary Cooper, Winston Churchill, and many other movie stars and VIP's stayed there during its haydays. We stayed there once, but always go to sit at their patio-bar to enjoy a Cuban cigar and drink. The ambiance is unique, and it's a great place to meet people from around the world - even Russia. One of our favorite restaurant, La Guarida, is not only a good restaurant, but one of the famous ones in Havana.

We saw Susan Sarandon once; she walked into our dining room, turned around, and left. If I had my wits with me, I would have invited her to join us. My buddy and I have traveled all over Cuba, so we know the country pretty well. Would love to go back, but I doubt my wife will let me. Any questions? Would love to answer if I can.
