I can’t remember the last time I saw an A&W Root beer drive in or a Shakey’s pizza in the U.S. but both are all over Japan.
There's still an A&W Drive In on I-94 in Southern Wisconsin. Been there, it's great.
The last Shakey's Pizza I've ever seen was more than 20 years ago in Orland Park, IL - not far from where I live. Ate there ONCE, it was positively CRAPPY pizza! I didn't think it was possible to find something worse than Domino's pizza, but Shakey's was it!
