Just wanted to add to what Shanan said. I tried booking this tour a month ago for a feb dinner and was told 1. You cant book this any farther out than 30 days and that you should book it as soon as you can at that point because it fills up. 2. If for some reason you are the only one booked for a date , they will inform you near the date that it is cancelled but that is extremely rare. 3. You will have to pay with credit card at time of booking. 4. As of a month ago they said they were only offering lunches and no dinners but that may change. 5. It is offered only on certain days.
You can book it through dining res or tour reservations(although they dont consider it a tour)
