I went to Cuba in the 1990s. Everyone appeared well-fed and in good physical health. There were no visible food shops such as supermarkets (but people walked out of back streets with unmarked plastic bags of what I presume were food and groceries). People were living in rooms of buildings that had undergone no renovation since 1959 (and no longer had glass windows). Most cars still dated from the same period, and had been kept going. Public transport looked to be problematic (very large truck-buses were being used, but did not seem able to cope with peak demand). Plenty of tourists (especially from Canada). I don't know what it's like now.
