When I was in Denver last, they had 3 or 4 of them that all seemed to do pretty well. Basically these huge warehouse spaces sub-divided up. Some of them even had full fledged restaurants, art studios, breweries, coffee shops, etc.

The "landlord" usually puts a bar in the middle, which is obviously the highest margin part of any restaurant. They get the benefit of making money on drinks and events, plus they give patrons a great reason to come there to drink with so many food options.
