I saw one of those in Belgium. The guys riding it looked like they were having fun

Another Minnesotan? 

Pedal pub is cool if you don't mind going 3 mph between bars, but you can hop on a bike and get there a lot faster (and cheaper too!)

I've seen this bike for years in Amsterdam and would love to ride around the city, pub 2 pub ..

That type of bike looks similar to what I saw in Times Square NYC.  The bike taxi drivers wore various costumes.

The Bike Taxi driver was a 6 foot 4 inch tall African American dude wearing a Wonder Woman costume, complete with matching golden boots, wrist bands, tiara, and lariat.

Except there's a bar attached...No need to rush.
But, yes...Not a cheap alternative to traditional transportation.
