Hollywood Canteen

The Hollywood Canteen was a diner created in 1942 to serve food to soldiers who passed by the city while on their way overseas. It became a popular hangout location for both soldiers and locals, including actors.

History
Piper Halliwell visited the canteen twice looking for then-mortal Leo Wyatt. Knowing they couldn't meet until after he died and became a Whitelighter, Piper walked up on the stage and sang "Sentimental Journey", a song that Leo heard and stuck with him until he died.
