The key to this being viable is what other types of attractions you can come up with to bring people in either earlier on game days, or on non game days. You mix in dining type amenities once you have a reason for people to show up besides food, if you don't have a significant draw then in terms of generating new tax dollars to pay for stadium upgrades. You try and keep most of your parking because part of the draw is it functioning like an alternate downtown without parking headaches. If you had a really good transit option that would be great as well. Since the light rail went in to downtown Minneapolis I've only driven through there 1 or 2 times, riding a train is so much easier (and cheaper).
