Ahoj Janó,
thank you for your question about the Czech cuisine.
As for the fried cheese, it's not mozzarella cheese, but it can be Camembert or Eidam cheese. Most often gets served with boiled potatoes and salad side dish in restaurants. As fast food they tend to sell it with fried potato chips. I prefer the restaurant type.
When you visit the Czech Republic, you will notice that most traditional meals consist of some kind of meat (duck, pork, beef, chicken) accompanied with dumplings called ''knedlíky", or potatoes ''brambory'', or rice ''rýže". Sometimes mashed potatoes.
There exist several types of ''Knedlíky'', salty ones made from potatoes, or made from flour with texture resembling roll bread. These are cut into flat slices. Other ones are sweet rounded Knedlíky filled with fruit. Some people eat them as main dish, some have them for dessert.
You can google up dishes with dumplings, such as: svíčková, vepřo-knedlo-zelo, bramborove knedliky s uzenym masem, segedínský guláš, with rice: španělský ptáček, kuře na paprice, kuřecí játra s rýží....
Here are some links in English that you can have a look at.

Have a great trip to the Czech Republic
