Dirty Pretty is a fun place to go to, especially to listen to some live music. To be honest, I do not compare it to bars such as Suede, PCL, etc, because it is simply not the same.
Is the crowd similar? Yes. Younger, more Scottsdale-like. Yes. If you don't like that "vibe", I would suggest to stay away as you will most likely not be able to look past that. If you can look past the lame stereotype, I think you will have an awesome time.
The music is awesome. Live and loud, the way it should be. Last time I checked I like my live music loud. The drinks are solid and the service is awesome. The venue and decor is great as well. All around awesome place...
