Sport is a religion in Cuba. Watch the amateurs play in the day or evening in one of the hundreds of local fields and parks. Havana has them all over,especially in Vedado. It's great, cheap, entertainment.
The lineups can get long at night to enter some of the most popular state restaurants and cafeterias. This is Valentines day, so everybody wants to go out for a bite. The rule in Havana is, if you want to get a seat, go early, especially on a busy night. This place in particular, at the corner of 23 and F, in Vedado, is not even a fancy place. It's a cafeteria selling hot dogs and burgers.
Avenida de Los Presidentes at night is fantastic. It's a top action spot in the city. Just come here and relax on the benches and listen to the locals play music. Grab a beer at the outdoor bar. Make some friends. This is the place to be for a great evening in Vedado. Learn about other fun , cheap places, in the guide.
