we did YC with our DD4 last November. For TS, we did Coral Reef (excellent), Mama Melrose (average), Cape May Cafe (dinner - good), Hollywood & Vine breakfast (early - DD4 loved it), and Yachtman's Steakhouse (two TS credits, but we thought it was worth it and we all enjoyed it...it was NOT too "stuffy" for our DD4 - in fact, it was quite casual but with excellent service and food).
I know you asked for the BC area, but figured I'd give you our full TS list from the last trip and let you know that we had no problems with our DD4 in any of them. We thought everything was excellent but Mama Melrose's - it wasn't bad, but nothing to bring us back again.
Of those listed above, Yachtman's Steakhouse, Cape May Cafe, and Coral Reef are all within walking distance from BC (Yachtman's and Cape May are obviously in the same complex).
I also recommend grabbing ice cream at Beaches & Cream. We grabbed it to go one night and watched the "higher" portion of Illuminations from our balcony as we enjoyed our ice cream!
Have a great trip!
