Unlike the rest of the world, in the Czech Republic we don't drink green beer only on St. Patrick's day but according to own tradition also on Zelený čtvrtek (English word for this day is the Maundy Thursday).
There was Černá Hora pivovar Green Beer on offer at Lucky's on April 5th. I didn't manage to find anything about green beer from this particular brewery, I only found couple of articles (in Czech) about Starobrno's green beer, which is the biggest producer of green beer in the Czech Republic.
If you are interested in this topic, you can find couple of links below.
