One Yelp review comments on how much they loved the Salt and Pepper shakers, and, we believe, these were them:

Sudden Closure and Legacy

On August 18, 2025, the Lipans announced an abrupt permanent closure via Facebook, effective immediately after weekend service. “Twenty years of blood, sweat, and tears,” Todd wrote, citing burnout after two decades of 5 a.m. starts. The final day drew emotional crowds, with lines wrapping around the building. No successor was named for the space, though rumors swirled of a possible national chain takeover.

Two Dog’s void is palpable—locals mourn the loss of Longmont’s “best damn diner,” a rare gem that outlasted countless competitors. Its legacy endures in the countless memories and the indelible mark on the city’s culinary scene.
