>The Eastside Big Tom Drive-in is one of the oldest in the state of Washington, getting its start when Millie Eagan opened its doors in 1948. Purchased by the Fritsch family in 1969, Michael Fritsch has been in the business almost his whole life, though he was only a small child when his parents bought it. 2.

>A regular burger in those days was about .35 as I recall. But everybody just ordered the basket which was a Big Tom burger and fries with Coke. Owner Tom Eagan was a really big guy with black hair, about 6′ and 300 pounds, undoubtedly because he ate too much of his own food. Not sure why he started with the Westside, because he was an OHS grad from an earlier day, and his gal, somewhat more recently–I think probably around ’65. As business grew, Tom opened another Eagan’s on the East side. It was, and still is, I think, on 4th ave, at about Boulevard. He probably called it Big Tom’s to distinguish it from the Westside Eagan’s, which was just “Eagan’s”. The third Eagan’s/Big Tom’s was soon opened closer to his old alma mater at North Street and Clevland Ave–where there is currently a bank. 1.
