Pilsner Urquell brewery in Plzen — 90 minutes by train, the source of the original lager (1842). The brewery runs three tour tiers; the bachelor's pick is the Original Tour with the unfiltered cellar tasting. Day two: U Pinkasu (450-year-old beer hall, the first place in Prague to serve Pilsner), Lokal pubs (5 locations, the modern proper Czech pub revival). Day three: Charles Bridge dawn walk, U Flecků (1499 medieval brewery + restaurant, dark wheat beer the bachelor's pick). Sleep at the Pod Věží (Charles Bridge overlook). Prague (PRG) is direct from major US East Coast.
