This sounds like something fun to try, when I have $100 to throw at one dinner. The servers are blind, which gives them an advantage over most of the diners in a completely dark restaurant. Sure, it's a trendy idea from Europe, but it sounds like fun. I emailed them, and they can accommodate vegans too, just specify with your reservation.
Warning, has background music I found no way to turn off without muting my computer's volume.
