For me that was "COM Computers", which was like a small department store in that it had 4 floors (they also called themselves "the first computer department store".
On the second floor there were the Amigas and STs, and a bunch of teenagers, some of them crackers and demosceners hanging around each saturday, and copying disks and playing games when nobody was watching.
These days that building is a huge shop selling all kinds of lamps...
