I use to like Old Town Alexandria for the restaurant scene. But it has been a long time since I was there so my info is obsolete.
I use to go to Winston’s in Georgetown just a couple of years after Susan Ford was a regular there. Susan married a Secret Service agent from her father’s security detail. Now Winston’s is no longer Winston’s but even Google Earth labels the Exorcist House and Exorcist Steps. The Tombs in Georgetown which also appears in that film was “temporarily closed” for the scamdemic even while other nearby restaurants were still open. John F. Kennedy officially proposed to Jackie at Martin’s Tavern at the corner of Wisconsin and N Street and it was still open in July while the Tomb’s was closed.
Richard Nixon was also a regular there. When I ate there in 2019, I wanted to sit in his booth, but someone had already reserved it.
I spent many an evening at Winston’s and The Tombs in the early to mid seventies.
We probably spilled beer on each other at some point.
