I originally wrote a closing for Doc's Gumbo Grille when it moved from 1115 Assembly street to the old French Quarter Deli location on Rosewood Drive. That closing was on 31 October 2009. Commenter Barb says the new location closed 30 December 2010, meaning the new location lasted just a bit over a year. As I mentioned in my other closing, the menu at Doc's wasn't up my alley, and since this location didn't host any Swimming Pool Qs shows, I never dropped by.
I know the original Keg O' Nails lasted many years in this location, but I don't think The French Quarter lasted very long -- it may be that this is just not a viable location any longer, or it may be that the market is so different from The Vista that the Doc's concept just didn't fit here..
For now, the the Doc's web site is still up with a nice little thank you message.
