^^^ Both of those developments sound awesome. I doubt I'd go to an all vegan grocery all that often, but having it right next to a Rail station would be terrific.
RE: The TV Museum, he wants to be in Downtown proper. He wants to be within walking distance to the Convention Center. The thinking is that Convention visitors who aren't renting cars don't have many entertainment options. This museum isn't going to be particularly large (only about 1/5th the size of the MIM), so its the sort of thing people can do on a break between meetings at a convention or whatever.
He also wants to be in an existing building, preferably something warehouse-y that can kind of feel like a TV sound stage. I'm not sure how much new construction he's willing to do. The problem with that is, there aren't a lot of 50K sq feet warehouses in Downtown. Once you head South of Lincoln there's plenty, but thats getting a bit far off the beaten/nice path.
This building I think most closely meets his needs. Its 43,500 sq feet, but it can be expanded and even have levels built on top of it. Its just South of the Madison/St James and would make an awesome gateway into the Warehouse district.
Other possibilities would include:
The Circles Discs and Tapes building: Its an awesome building, right on the LRT line, and would be great w/ 1st Fridays. But, its too small, only 36K sq feet. They'd have to expand by building a new 2 or 3 story structure on the parking lot just north of Circles and I don't know how much Comisar wants to get into new construction.
The Luhrs Central building. Its the lower scale white building just south of the Luhrs Building and Tower. A few years ago it was slated for demolition as part of the Hanji hotel project which never happened. We heard tales of it being structurally unsound and too expensive to rehab, but who knows how true that is. I'm not sure of the exact square footage, but it looks much bigger than the 1st building I posted.
Also possible would be the 2 red brick warehouses on 7th St. at Garfield. One is currently home to Core Crossfit, the old AJ Bayless building. The warehouse just South of it until recently had a florist in it, its now empty. The South warehouse is 7500 Sq feet, the north is about 10K I believe. So they'd have to do quite a bit of construction there and plop a new structure between the two existing structures on the parking lot. That currently empty warehouse may be a better place for the preview center than the larger full museum.
