Was there two years ago. A very enjoyable experienc.e A country with lots of contradictions. great warm friendly people and lots of double standards. Lots of pluses and some minuses.
As for beer - not much of a choice really. Most beer available is either Cristal or Bucanero, both lagers about 5%. I preferred Bucanero, more dark in colour. Many bars would just have small cans of same. All breweries and hotels/most bars are nationalised so that speaka lto for things re choice. Did not see any draught in my travels. Some European mainline beers but nothing very exciitng. I did not try any wine but they impoft some from Spain and their own is supposed to be o.k. Try the 5 or 7 annos Havana Club rum, and the mojitos, mojitos made with fresh mint there are really good and thjey take great pride in making them. . Food si so so except for superb lobster, Other than that chicken or pork, some fish and that't it! Not sure where you are going but have a great time. Give me a pm if I can offer you anyother info. Also reocmmend Lonely planet or rough guides of course too!
Overall a great experience. I did not stay in a tourist resort as man do - went with a trekking-type company, . Less comforts but more of a a real experience!!!
