One word: Kitsche. I was looking for a fun dinner "experience" to treat my daughter to. This place comes up in every family dining guide and I guess it's because only kids under 7 would not be completely horrified by this place.
First of all - cash only. You stand in line to order. The food is overpriced and very sub-par. You have to cram yourself in on a bench next to strangers (unless you have a group big enough to take up the whole table - maybe 6-10people?). You will probably lose your seat if you need to get up and order another drink or use the restroom.
The organ plays... Interesting... Pieces of music. It *is* cool to see how different parts of the room sync with the organ/music as it plays. However it was not worth the overall experience of being smushed next to strangers, overpaying and eating bad food.
I will admit - my daughter was enthralled by the "finale" song of each set - where they blow bubbles and the disco ball comes out and it's like a 2minute party in the room. But again... Not worth it. It's 2 min of smiles and 60min of torture.
