As for La Mexicana, it is a butcher's. However, as this is Cuba, there is only a small amount of meat available at subsidised prices, as indicated on the chalk board above the cash register.
In spite of what was painted on the wooden board, the butcher's was closed when we passed there at around 9:30 am as there was no meat. It did not seem to have had any the previous day either, the last date entered on the chalk board being two days earlier.
