I went to my local HoJo’s a few times. ( It’s probably been 35 years since) But, I just didn’t recall the chain as a stand alone restaurant.
I saw a few. I guess the last one, that just closed, is also a standalone.
The last one I was in was in Newport Beach California and Buddy Ebsen was at the next table over with his two teenage daughters that I went to school with. That tells you how long ago that was !!
