I wrote about my experience on TripAdvisor as well. My article was published but now seems to have been removed and put back into pending review so does not appear here:

I also noticed that others had a similar experience and had written about it. The difference was that another reviewer (also in a group of four) had been told about the minimum spend PER PERSON and left. Their reviews have also been removed at this time. All very odd.
