You can't really go wrong with a continental/buffet breakfast, especially since it was included in the hotel room package. It is like a choose your own food adventure. At the Hotel Vedado. Lunch and dinner are best eaten on the road. There are many eateries in Havana; except salty food, no take out containers and no condiments. As with food in any foreign country; expect the unexpected.
Currently Wendy's is leading the race as the most expensive fast food joint you can visit in Jamaica. Don't buy any of the cheap items because they are basically kids meals. Shell out big or go home. It's good though will return next month or next year.
