Startup Idea : Feel | Bar And Restuarant Stats in Real-Time

Bar and restaurant demographics are constantly influx. We blindly pick and choose venue's hoping that by the time we get there, the scene compliments our current moods. However, this strategy doesn't always pan out (too many guys at a club, the venue is not diverse enough, too many couples, not an attractive enough scene, bad music, etc). What if we could know demographic and behavioral information about any specific venue in real-time? Feel, would allow users to rate a venue's feel in real-time. User's would authenticate the app through Facebook, which would allow Feel the necessary information to provide real-time venue statistics to other users -- allowing them to make the smartest venue decisions to compliment there current moods.
