Dan & Louis Oyster Bar is a seafood restaurant in Portland, Oregon described by Fodor's as a "Portland landmark. As its name implies, it specializes in oysters — from Yaquina Bay and beyond — served raw and in an oyster stew the restaurant has been known for since 1919.
The restaurant has been in business since 1907 when it was founded by Louis C. Wachsmuth as a raw oyster bar. Louis was the son of Meinert Wachsmuth, a Danish immigrant who had farmed his own oyster beds on Yaquina Bay. The bay became the home of a farm, the oldest in Oregon, established to provide the oyster bar with a regular supply of oysters.
The menu was expanded in 1919 when Wachsmuth took over the food bar of the Merchant's Exchange Saloon. Dining rooms were added in 1937 and 1940. The restaurant remains under Wachsmuth family ownership into the 21st century, and is currently operated by Doug Wachsmuth, along with his wife and brother.
