I had the Champagne only - no dinner. The show is worth the price and your time. The dancers and performers are top notch. You will see well-done classic artsy French dance acts as well as exciting updated bits. Cirque du Soleil type bits as well. You won't regret it. Kids attended at well. here is their website. They are only a short walk downhill from the Cardinal Lemoine Metro station and are next to the building with a Mercedes emblem.

Nice tour once you get on the bus!! Best to start at the Masarykovo station (Stop 2), since if you meet at Old Town, you need to do a long walk to stop 2 advertised as a walking tour, but soon will be obvious is really a good jaunt from where buses are not allowed (but walking tourists abound) to Masarykovo station where the tour actually begins.
