You book a 4 hours plus - Istanbul Luxury Bosphorus Dinner Cruise with fantastic shows that you are supposed to remember for your life.
What you get is a normal tourist boat - nothing luxurious about it what so ever, poor food - and poor shows.
Tourists should focus on the Arabic tourist boats, same kind of boats, but better food and shows. The Arabian operated boats deliver what you book, and you don't have to feel that you have wasted time and money afterwards.
I would have given them one star, but one extra star that they got hotel shuttle, and the personal on board gave nice service.
