I believe we got served 'tainted alcohol', the same kind tourists in Mexican resorts were served.
We came here on a Thursday night and each ordered one drink. I felt immediately bad after an hour and was feeling poisoned the next day. My lover is of German ancestry and holds her liquor well. However after one drink, she was feeling bad the next day. This does not happen to her.
On another note, the games seem fun to play but were rather expensive. The whole place seemed rather empty on Thursday night. Maybe we should have taken a clue.
Update 12/10/2017: I received several message responses from other patrons who had similar experiences.
