I think the thing with AAA is that the agents sincerely believe that they are getting clients both discounts. When I booked with them, the TA told me that I had the
free dining and the AAA room discount, as well as the ticket discount, but when DH and I sat down and did the math, we did get *only* the free dining. I am not complaining by any means, the free dining is a great savings, I would just encourage people to sit down and do a break-down of costs, because I think though the AAA TAs think they are getting the multuple discounts for clients, they may not be. Even after I mentioned my figures to the TA she was still asserting I got the other discounts, but the numbers just didn't add up.
That aside, I would go to any restaurant that strikes you, esp. since it is *free* anything you get is a savings

We were thrilled to see that the Earl of Sandwich is now on the dining plan. It isn't pricey, but we love it, so we'll be going there. I would just find places that have the foods you will like and not worry about the best value for the plan, since anything is a value with it free.
