D found Krusovice cerny at BevMo*. It isn't my beloved Staropramen cerny, but it's pretty amazing. Cerny (which translates to black) beers are dark and just a teeny bit sweet and caramelized but not as smoky or as coffee flavored as you sometimes find in dark beers.
Prague ruins you for life, guys. Nothing else is ever good enough.
*Looks like they're currently sold out online, but he found it at our local store.
