There's a great restaurant chain called "Dans le noir" - I went in Barcelona, but there are several. You dine in total darkness, and all the waiters are blind.

There's a great restaurant chain called "Dans le noir" - I went in Barcelona, but there are several. You dine in total darkness, and all the waiters are blind. They don't tell you what you're eating or drinking. It is amazingly hard to tell - most people couldn't guess what they were eating, and no-one could reliably tell the red wine from the white. I'm a total wine peasant, but this included a guy sitting at our table who worked in the wine industry. It's a highly recommended experience, it's really interesting.
