Sorry if this is repeat advice for the original poster...I didn't read the entire thread cause I don't want to get into the debate of whether or not you should take a crying child out of the restaurant.
My DD is 15 months and we're just starting to see it now, so my first thought is stranger anxiety since you said it the entire time you're at the restaurant, not just after your child gets antsy. Try bringing your child's comfort items with them and give them at the restaurant - a lovey or a pacifier. Perhaps sitting in your lap until the food comes might be comforting enough and then into the high chair to eat and the food might be enough of a distraction.
Good Luck.

By 4 years old my kids could ride almost EVERYTHING at WDW. At 4 years of age, Tower of Terror was my middle daughter's favorite ride (and still is)! Most kids are 40 inches by the time they are 3 1/2 to 4 years old (not all, but most) and can ride and enjoy most everything in the parks. The only attracations my kids could not do by 4 years old were Space Mountain, Mission Space, Everest and Rockin Roller Coaster. So that's 4 attractions they could not ride, out of the literally hundreds that they could. And for those 4 rides we, and anyone else for that matter, can to Rider/Child Swap.



But I may pack the white noise machine anyway...AND request a non-pool view.
