Yes as above, hit Parque Central. They also have Jack & Coke/diet there. Get a pizza at the pool upstairs, its really good.
If you like clubs, hit the Libre Hotel. Mini- Fidel parties there with his entourage of women. It's awesome!!!
Also, grab a mojito at that fort thing on the water.
Hit China town, its a crack up seeing chinese cuban food. LOL
Alcapone has a hotel you may like visiting, it over looks the ocean, really nice view.
If you like the resort life, go outside Havanna and hit Verodero and stay at a resort. To me its a little boring but the beaches are topless.
Cuba is definitely a place to see before it gets Americanized and becomes Vegas.
I'm going to probably check it out again in a few months again!!!!
