Copper Kettle and Iron Skillet used to be owned by the same family. I was their paper boy back in the 60s. I don't think there's much to choose from between them and Hollyhock Hill. I've never gotten even a mediocre dinner at any of them.
I'll give another thumbs up for John's Famous Stew, St. Elmo's, Shapiro's, Bazbeaux. I also prefer Muldoon's to Bub's.
