Translation: You should try fried cheese.

I laughed at this. This sentence is SO Czech.

"you should try a fried cheese" .....špatně ....... proč tu nemusí být člen?

[BjrnMrtens]

We're talking about fried cheese in general, the concept of fried cheese.

If the context was, say at a party and someone came over to offer you one of their fried cheeses, then the article would be appropriate.

I can't explain it better I'm afraid. Hope it helped!
