Chocolate addicts, beware: this state-run museum-cafe in Habana Vieja's heart is a lethal dose of chocolate, truffles and yet more chocolate (all made on the premises). Situated – with no irony intended – on Calle Amargura (literally, Bitterness St), it's more a cafe than a museum, with a cluster of marble tables set amid chocolate paraphernalia.
Not surprisingly, everything on the menu contains one all-pervading ingredient: have it hot, cold, white, dark, rich or smooth – the stuff is divine, whichever way you choose.
