We really liked Sticky Fingers on HHI. It was probably our family favorite! The ribs were SO good, and it had a great kids' menu. One of my sons doesn't like for the usual kids' side, fries, and was pleased to be able to order mandarin oranges instead. I would recommend going early, though... There was no wait when we got there a little after 5, but a long line by the time we left.
Ooops! Just read that you were looking for "within walking distance"... Sticky Fingers is a short drive, but worth it!
We ate at San Miguels and Scott's w/in walking distance...Both were good! The kids liked Sticky Fingers better, though.
