hi there,
Cuban restaurants include "paladars", which is essentially a private Cuban restaurant and it is a common option when looking to explore Cuban cuisine.
As you might imagine, finding paladares is easier in bigger cities like Havana and Santiago de Cuba, though they can generally be found at just about any destination you will arrive at.
You can also find
fast food restaurants such as "El Rápido" (the Fast One), which serves burgers, pizzas and things that.
Most provincial capitals will have both fast food restaurants and paladares, both of which can be quite cheap. For a quick bite, you might head to a Pain de Paris store in the cities, as they serve up some nice croissants, sandwiches and other delicacies.
Chinese food is on the rise in Cuba, and Havana even has its own small Chinatown, which is found in Central
Havana.
