Okay, I've read with interest the Columbus Sandy's site info as well as the info on the ColumbusTour page, but I have to let you know there was an additional Columbus location that you have not listed - it may well have been the 1st or 2nd Columbus location and (probably) ceased operation before the 1968 listings in the phone book.
I was born in 1955 and lived in the north end of Columbus, OH and I recall my mom taking me to Sandy's in her brand-new 1963 Plymouth Valliant - she made me eat my plaid-and-white wrapped burger outside so as not to soil the new car!
The building is long gone, but it was on the north edge of the Northern Lights shopping center, which would give it a Cleveland Ave. address. I will endeavor to figure out an address that it would have had.
A co-worker has confirmed my memories as he remembers munching on a burger and fries while hearing the results of the Nov. 1964 presidential election on the radio. He also states that there was some difficulty in accessing the restaurant easily due to the adjacent shopping center not permitting some kind of access, so that could be a reason for its short life - it never was there long enough to become a Hardees.
Both of us work here in downtown Columbus.
I will report back to you with the results of my detective work.
