When we ate there back in September there were 3 dancers, 2 girls & 1 guy. They all 3 danced at the same time, 2 on the stage area and one on the table in the middle of the room. We sat right next to that table! It was awesome. I think it starts at 7 and it kind of alternates with the music then the dancers. We saw them perform several times. One of the girls even did some ballet stuff on the stage.
We went back last month and there was only 1 female dancer there that time. Again we sat really close to the table in the middle of the room where she performed. (We got super lucky both times with our tables, I didn't request anything special.)
