I'm sure you get these types of posts quite often, which I apologize, but I thought I would get some hopefully honest feedback.
I'm located in Springfield, IL which is practically the middle town of 115,000 people between Chicago and St. Louis on a highway that runs through both cities. The town is a huge sports town, and split between Cubs and Cardinals fans, Blues and Blackhawk fans, and Bears and Rams fans.
The only true sports restaurant we have in this town is a buffalo wild wings, and this town will break you if you open a restaurant that does not stand out or have a good location to it.
With that said, I've been toying around with an idea of a sports bar that's rich with both St. Louis and Chicago sports. To go along with this idea, I was thinking of having 2 parts to the menu, one side would be all Chicago famed dishes, and the other would be dishes that sets St. Louis apart.
There's a heavy traffic area being built and almost finished right off the highway where a large Scheels sports store is being built. I'd love to hear what your opinions are for just the beginning process, or if I should even entertain the idea. The restaurant would be called "Rivals"
