Museo del Ron:The Museum of Rum is not a rum distillery, but rather a short walk-through of Havana Club that ends with a rum tasting. The tour explains the entire rum production process, starting from the sugar cane, and includes a very sobering analysis of colonization, slavery, and economics of Cuba. Your tour will likely also include some sardonic commentary about the embargo’s effect on Cuban popular opinion.
The Hemingway haunts: If you're an Ernest Hemingway fan, you'll want to check out the salmon pink Hotel Ambos Mundos, where he lived for seven years, and grab a daiquiri from the (also salmon-colored) Floridita, Hemingway’s favorite bar. His residence, Finca Vigía, is also located in Havana and is now a museum.
