Opaque at the Hyatt
I take my students every semester and everyone has a memorable time.
I think its worth doing at least once. The sensation of total and complete darkness is unforgettable. The food has been upgraded since their inception several years ago. I find the beef and salmon dishes to be the best. The $100 for the food alone is probably not a good value proposition, but for the entire experience, I'd say, try it once. The darkness does something interesting to the quality of conversation.
...and for couples, let's say there is a seriously under-rated erotic quality to the evening. After all, no one can see you!
Your right it's more about the sensory experience than the food. You first order outside the restaurant, then your lead by a blind waiter by holding his/her shoulder to your table. It's completely dark and everyone is packed in the restaurant. You have to figure out how to eat without spilling or making a mess. It takes over an hour to finish.
