A Cuban sandwich (or just a cuban) is easily found in south Florida. It is made most commonly from Cuban bread, ham, Swiss cheese, mustard, tomato and pickles. After the sandwich is constructed, the outer part of the bread is brushed with melted butter and is pressed between two heating elements covered in aluminium foil. This warms the insides of the sandwich and makes the outside buttery and crispier with a nice golden brown look.
You may find some sandwich shops that put roast pork and/or salami in the midst of the ham and cheese. It's good! If you have the chance, try a Cuban sandwich! It could be consider's Miami's answer to the Philadelphia Cheesesteak!
The great GangstaFeelsGood says that you can easily find Cuban sandwiches in New York City.
