I understand. Czech cuisine is very similar to German cuisine: plenty of sausages, pork, duck, rice, potatoes, potatoes, potatoes, cabbage. Not many veggies. They have a side dish that they eat a lot, called KNEDLIKY. It is like a dumpling and basically tastes like whatever sauce or gravy you put on it. Very bland and filling. The better knedliky are the ones made from potato (bramboré knedliky), not the plain flour ones. Another typical dish is SVIČKOVA, basically beef in a creamy, sort of sweet, sauce. An acquired taste. If you are into soups, I would recommend KULAJDA, potato and mushroom soup flavored with dill. A classic of Southern Bohemia.
Once again, not a fantastic culinary destination but, yes, a fantastic city like @tassojunior says. I lived there for 4 years.
