Just by walking around Havana by night, you will find many bars and cafes which have a live 4-5 piece combo and audience participation is encouraged. The prime area for this type of entertainment is in old Havana. Again the quality and entertainment value can be exceptional. It's not easy to explain but great to see. As you enter the country you feel like you are back in the 50's.
Vintage cars are all over the place - still in great shape.
It is also located in the best area of Varadaro since all the action is there. The club gets packed every night. After midnight they play salsa every so often. The club is open till about 4 or 5 in the morning and believe it or not, people stick around till then. We also went to this great outdoor club down the street called Castillito.
