"The Shamrock Grill" was at 1362 E. Livingston Ave. . I ,sort of, remember it being on the south side of the street, and either before or after another "gin mill" I use to frequent, "Heinmiller's". It's one of those bars, I remember passing, but never went in. I remember that it looked like an interesting place. (Couldn't hit 'em all)! Don't know what happened to it. The "Shamrock Lounge" was at 791 W. Town St., was in Franklinton, on the near west side, and I probably did "cross its doors" at one time, or another. Don't know what happened to it, either. Funny how places where we debauched are gone......but, not forgotten. ( They don't last forever ). Hope someone else can help you more. Blessings!
