Awwww! I hate to hear that, Mike. Like you, I liked the place a lot AND hadn't been for a while. (Mary used to go fairly regularly with some friends, though.)
Christopher Seckman, the owner of North End Cafe, was the original owner. I don't recall having heard that he was out, but what do I know? 
Meanwhile, it doesn't look good.  No answer on their phone (502) 614-6567, although it rings through, doesn't appear to be disconnected.  No mention on their Facebook page, but it had been fairly active with near-daily posts until August 31, and not a single post thereafter. Last Instagram post, same day. Last day of the month: Gave up their lease at month's end?
