Hadley in Orange County?
I'm not sure if I'm remembering correctly but was/is there a Hadley fruit stand/market in the South Orange County area, maybe around San Clemente, off the 5. I know there's the one on the way out to the desert. I really could use one of their date-banana milkshakes.
You might be thinking of the one in Carlsbad. It looked shuttered last time I was in that neighborhood. Both Carlsbad & the one in Cabazon are handled on the California board.
To keep this on topic, I will second the recommendation for the shake shack that torta recommends above. To correct her inadvertent typo, it's a Ruby's owned joint, not Rudy's.
