My friends and I went for a birthday and we had a great beginning to the night, the servers were great but my one friend was enjoying himself and decided to yell along with the music and apparently that is NOT accepted by the security because immediately 3 of them went after him and took him outside aggressively and ripped his shirt until me and another female friend screamed at them to let him go and we left. It was all over absolutely nothing and we have decided to SPREAD THE WORD AND NEVER GO BACK. Go to DALLAS for a good time...
