A casino at that spot - not that I'm a fan of the idea - would make sense as the Convention Center casino, as it's a 10-12 minute walk. It does not make sense as a casino-retail playground for suburbanites who can get such things elsewhere, as is obviously envisoned given the (oh sweet jeebus this is the big one) 2000 parking spaces. Rooftop retail? Oh Lord. Go ahead and build it, it'll go under in less than 5 years.
