I would say the food at La Habana is not really Cuban but Caribbean Cross Over. I've been happy with the food most of the time although it's not really sensational.
The music is always good and the rum cocktails are really good. The mojitos are more like the ones you get in Cuba than the ones you get at all posh cocktail bars. The cellar bar is a bit rough and gives me flash backs to Havana.
The spontaneous dancing and mix of Latinos and Swedes is usually quite good as well.
A good time is promised for all.
