I know of Don Roth's, which just closed within the last year.
There was Don Moy a chinese restaurant in the NW suburbs but thats been gone 10-15 years.
We always had our last dinner out at The Palm Restaurant at the Drake Hotel, when I was up for the RAC (Retail Advertising Conference). I’d understood that it moved to a different location. Fine place, and old.
My mistake on the name of the other place, it was Bob Chinn’s out in Wheeling.
