What was the name of the beer on Laverne and Shirley?

Answer 1

There was no 'bar' exactly on the show. However, the girls worked in a beer brewery called Shotz, and their hangout during the first five seasons of the show was called the Pizza Bowl (Laverne's dad owned the establishment). In the last three seasons of the show, after the girls moved out to California, the Pizza Bowl was replaced by Cowboy Bills as the girls' primary hangout.

Answer 2

Lead characters Lavern and Shirley both worked at the Shotz Brewery.
