This is maybe the dish most associated with the Czech Republic, "Smazeny syr," or fried cheese, with tartar sauce and one or another potato side, in this case baked potatoes. Usually it's served with beer, but it was a work day when I was having lunch at Havelska Koruna, so I ordered some kind of cola. In this case, I think the cola was Kofola, which is another traditional Czech product. Havelska Koruna, incidentally, is a traditional Czech "jidelna" or fast-food restaurant, serving traditional Czech pub food. Havelska Koruna is and was unusual in that it's located close to Mustek in the tourist area of Prague, and not in a working-class neighborhood where these types of restaurants would normally be located. More impressively, it's survived for the long-haul, as it is still in business today:
