Twin Falls A&W on Addison Avenue shuts down

The A&W restaurant located next to the Phillips 66 station on Addison Avenue in Twin Falls has closed its doors. Signs for the establishment are no longer visible on the building, along the street, or at the drive-thru entrance as of last night. The gas pumps at the adjacent convenience station remain operational.

The closure comes without a formal announcement, leaving many locals to discover the change by driving past the site. A reporter noted that while he lived in Twin Falls for 20 years, he had never personally visited the A&W on Addison Avenue. He described the closure as a surprise, though not unexpected given that he rarely heard recommendations for the location from friends or family.

Customers who did frequent the spot often praised specific menu items. A reporter’s son visited with friends over the years and reported that the milkshakes were good. Other patrons have claimed the cheese curds were superior to those served at Culver’s. Despite these positive reviews, the restaurant did not seem to generate strong demand among the wider community, according to local observations.

The building on Addison Avenue has undergone changes in recent years. The exterior sign paint transitioned from checkered brown to solid lines sometime between 2015 and 2018. The restaurant’s history in Twin Falls extends back further than its current A&W branding. Social media comments from long-time residents confirmed that the location previously operated as Mister Burger. Before that, it was known as The Mug or Frosty Mug in the 1990s.

Online records provided conflicting information during the initial discovery of the closure. An AI summary incorrectly stated that the Addison Avenue location was demolished in 2018, confusing it with the Mister Burger site on Blue Lakes Avenue, which is now the Renter Center. Residents clarified that the Addison site was the same physical location that housed the earlier Mister Burger and Mug franchises. A Google Maps photo from August 2026 provides a recent image of the restaurant before the signs were removed.

The Phillips 66 gas station next door appears to be open, with lights on and pumps active. The A&W closure adds to a list of local businesses that have ceased operations in Twin Falls over the past few years.
