I think so. The promenade was the coolest thing about the DS9 set. First, they could do camerawork that was unavailable to the other series. Second, it also made the sense of a public square in the future more concrete--there were real people who benefitted from the Federation, but also who had a say in what it did. Third, there was a sense that something new could be discovered or pop up overnight. New clubs, new venues, new restaurants, new merchants, … . Extrapolating from
@kkt 's comment, holographic technology could have been used to make the design and layout of not only flexible, but dynamic, allowing the customers to adapt their experience. Why wouldn't Quark want to have private dining rooms that could be reconfigured with a simple command?
I will always admit that Vic was at best a confusing inclusion. There were a few great moments from the character, no doubt: Here's to the Losers, Paper Moon, The Way You Look Tonight. Would those moments work without the other episodes? Arguably no. Perhaps more importantly, there is a significant minority of fandom who like these slices of holodeck fantasy. I could do without them, but I don't see any need to crusade against Big Goodbye, Fistful of Datas, or Badda Bing Badda Bang when others enjoy the temporary changes in tone.
Was Vic a strange choice? If you are going to have a Jazz venue, wouldn't it reflect the tastes of Sisko (and by extension, Brooks)? Brooks didn't seem to like doing holodeck stuff the way other actors in the franchise did. The casino thing may have been an attempt to bring back a little more of Our Man Bashir. If I were to have designed a venue for the station, my Jazz club would have been darker, smokier and funkier--and far less antisceptic, and definitely blacker.
