There are a number in the Los Angeles, San Gabriel Valley area (the San Gabriel Valley is north east of LA, the Rose Bowl is there.)
They also have a killer size serving of onion rings that's great!
Sorry I missed it while I was there.
My fave for pastrami and such in LA was Art’s Deli in the Valley.
“Every sandwich is a work of Art” is their motto.
Good stuff. Or at least it was back in the day....
