Beaver Valley Bowl is located in Brownsville, Pennsylvania. It is the local bowling alley.
Stanley Barber works here, and is often found at this location if he is not at school.
The bowling alley exteriors was filmed in the Beaver Valley Bowl at 25 New York Ave in Rochester. The building is a local landmark, and it was also used as filming location in the Farrelly Brothers 1996 comedy Kingpin and the 2000 movie Wonder boys. The watchtower top was built in a set and CGI'd into Brownsville's landscape. 
It can be noted that this is the location where Stanley tells Sydney that he is her 'mentor' after pulling out superhero comics. He then attempts to anger her in order to test her powers, but gets too personal and Sydney almost hits him with two bowling balls.
