Underground Bars

I was in two underground bars recently that were complete opposites of one another.  The first was a "ruin bar" in Budapest where young people would go underground to drink surrounded by amazingly old architecture.  The other was the cafe bar underground in the basement of the Musikverein in Vienna where old people would go to drink surrounded by very young architecture.
