Across 12 table service restaurants on our last trip, we were only charged for my toddler's drink once, at Raglan Road. We personally never asked about it or expected anything free, but were pleasantly surprised when most places didn't charge us. He was also given a free kids meal at CRT as well as the Bon Voyage breakfast, and offered additional kid-friendly fare (without us asking) at Ohana dinner, HDD, and Garden Grill.
