The only menu items that required a surcharge when we were there in Nov. was anything over $22, however, that only applied to one entree, which was the Surf and Turf. We loved our meal there. It was one of the best places we ate.
Yes, you do need an ADR or you risk waiting hours. I remember something about a fee being charged to my credit card if we didn't cancel within a certain time frame and didn't show up for the ressie. We are going to go on the dining plan and one of us will get the free entree that comes with the AAA package, so that will save one TS credit for later.
