Talk about a family affair: For five generations, the Wachsmuth family has owned and operated Dan and Louis Oyster Bar, keeping the beloved Portland, Oregon, landmark going strong since 1907.

When Louis C. Wachsmuth first opened his business, City Oyster Co., he ran it as a wholesale and retail seafood store that served oyster cocktails. He was no stranger to the industry—he had grown up working on his family’s oyster farm in Washington and learned to shuck oysters at the tender age of 5.

In 1919, Wachsmuth took over the food bar next door and added his now-famous oyster stew to the menu. As his customer base grew through the years, he added several small dining rooms, filling each with his growing collection of steins and maritime objects.

In time, the restaurant came to be known as Dan and Louis Oyster Bar, named for Wachsmuth and his son Dan, who was a constant presence in the shop until his death in 1938. Louis died in 1957, and over the next several decades, the restaurant’s ownership passed from one family member to the next.

While the restaurant has expanded a few times in the last 100 years, and new family members have taken the helm, its location in Old Town on Ankeny Alley has never changed. Oysters are hand shucked outside the entrance, as they have been for many years. And its nautical theme, with maritime objects collected throughout the decades, is a nod to the family’s longstanding place in the seafood industry.
