TREX is loud and obviously centered around a dinosaur theme. If they are not interested in dinosaurs, I would consider another DTD eatery. Rainforest Cafe has animal theming and doesn't seem quite as loud. Splitsville is also fun with bowling and eating. With so many dining options at Disney, I would pick something more appealing to the kids (unless you want to dine there and think the kids will like the Dino theme). My kids like it and aren't super into dinosaurs either. I don't have any complaints about the restaurant, other than the menu seems to be centered on meat items and not have a lot of selection.
