Potomac Fish House is a long-standing staple of the city of Mount Rainier. This classic fish sandwich shop has been around longer than most of us, since 1980! Store owner Mr. Kim originally helped his father establish his business on Rhode Island Ave. when Mount Rainier was just a budding town. Wanting to change the name of the carry out game in the D.C. metro area, the Kim’s chose Mount Rainier as their new spot and new home. With over forty years of experience, they’ve had time to perfect their cuisine and offer the citizens of the city a perfect lunch and dinner!
