I think it'll be an interesting place downtown. My only worries would be how it would operate during Artwalk, and Jazzfest. I'd really like to see some more interesting night spots open downtown though.
I'd assume they'd do great during those events because of the heavy foot traffic they provide.
I think the other poster's point was that ArtWalkers, hipsters, artists, musicians, and the like aren't really into places like Latitude 30 and I'd probably tend to agree...but I bet Latitude 30 will bring a different type of clientele and vibrancy to Downtown on other nights.
Even though the average ArtWalker isn't generally into places like Latitude 30, I could see if becoming a big part of Art Walk if they offer special deals or have special events like discounted bowling, cheap drinks, and combo bowling/video game packages.
I also wonder if they will try and make their downtown location a little more hip, urban, and artsy than the Phillips location. Its a great space that could be really interesting if they want it to be.
