Absolute genious. I am an HD sports fanatic, I would love for an HD sports bar to open in my area.
Put it some of those nice front projector sets up against massive screens...heaven on Earth.
I'd also keep a room where you sell HDTV sets on the side. First-timers will be so mesmorized by the quality that they may be tempted to lay down the dough on the spot.
I live in the DFW area. I have not personally been to a HD sports bar. A few random restaurants around here have screens, but they don't do a very good job of advertising their HD capabilities.
