Nice ... thank you for this info ...
We loved A&W, as kids ... Papa burger, Mama burger, Teen burger and Baby burger!
And, best black cow milk shakes, ever.
The newer versions just don’t compare :-(
The only Nathan’s we’ve had is from the one in Vegas ... at NYNY ... decades ago.
Never have had a White Castle burger. Good for them ... for sticking with what works....and, keeping it in the family for over 100 years!
A&W Rocked SoCal and they followed me to Arizona !
I Live a Blessed Life.
We had White Castle when we lived in Missouri (HS and college for me) mid 60s to 73. They were the butt of awful jokes about their quality, even then!
