In the article, his #5 is the Local Pub. But he didn't mention that part of it should be DRINKING the Czech beer (and other Czech specialities).
Pilsner was invented in Czech and their beers are great. (Budweiser is a descendent of Budvar, the original pilsner). There are quite a few local Czech beers to choose from. Our favorite is Pilsner Urquell. That's what we buy here to drink at home.

Another Czech find is Becherovka, a pretty potent liqueur made from 34 herbs (or something like that). It's good stuff too though.
I also tried "grog" from a street vendor. It was disgusting and I threw it out.
I didn't try it, but you can buy absinthe in Czech.
