GroundKontrol is a MUST VISIT. Any time I make it to Portland I have to go there. Word to the wise, parking is a PITA take the train instead it stops on the corner no parking nazis to worry about and over priced hourly parking. It's pure old school arcade goodness. I looked for Wunderland in Portland last time I was there and couldn't find it... the pics I found on the intarwebz were less than impressive IMO.
