I only frequented the Cafe Mediterraneum a handful of times while at Cal, usually because of the stifling smell of bleach, etc. Now Wall Berlin, or Cafe Intermezzo, on the other hand, was much more my jam.
And the people at the tables outside were a key part of the Berkeley scenery there on Durant!
I also was big into Caffe Strada.
Similarly, I never really felt strongly about Cafe Med, even when I lived near Dwight (Unit 2 and environs) and it was nominally on my way to/from campus.
The people that sat outside were always entertaining. There was a young man with a foot fetish that would constantly be asking women if he could see there feet. Unlike Oakland, Berkeley also had some of the most interesting bums.
