Here's the info I found:

129 Montgomery St
Montgomery AL 36104

Plus this info:

Mr. Cohen, the father of Dr. Nace Cohen, arrived in the early summer of 1906 on a small frigate from the Island of Patmos, Greece with John Costarides. They were legally sponsored by Petro Costarides, uncle of John Costarides and founder of Montgomery's Elite Cafe. Mr. Cohen was very successful in business, and at one time owned a hat shop at 30 North Court, Montgomery, Alabama

And possibly that Hank Williams played there, but not a word about a casino. Maybe it's worth a phone call.
