Re: In NOLA this week, heading to Audubon Zoo and park, sisko's outsid
I'd always assumed the Sisko's restaurant exterior was filmed on the Paramount backlot or at another studio, not on location in New Orleans. I don't have the entire series though, so maybe they did slip a stock footage shot in there somewhere.
But even if it was just a backlot facade, you could always give yourself a sightseeing trip in the vicinity of the park to see if any of the architecture resembles that seen in the show.
