Various restaurants in the area are participating for the week of Oct. 16 to Oct. 23. Cost ranges from $35 to $45 per person depending on the restaurant.
Though the fixed menu is somewhat frustrating/can be limiting, all restaurants do offer three different choices for each course (appetizer, entrée and dessert). You can view most places' menus online, which I recommend doing before making a reservation so you can make sure there's something on there that you'd like.
