Yes, it is kid friendly overall. And actually, they have pretty good food for the price. The kids chicken fingers are awesome! They also have a chicken appetizer that is great for adults, and also pizzas. So you don't *have to* spend a ton of money to dine in comfort and enjoy good food. Last time we ate at the Spice Mill and it was extremely expensive (like $7 for a PB&J and our adult entrees were aweful.)
They *do not* have any crayons or anything for the kids though. So if your little one is a busy body you may want to pack some stickers, crayons or something similar to entertain him a little. Otherwise, the sharks are neat to watch and they bring bread out early.
Enjoy it. For the price of some of the other restaurants, I recommend Sharks the most. Next, for the price & quality, would be Mango Joe's next to Wild Arctic. They have healthier wraps, salads and fajitas. (as opposed to fried foods.)
Have fun!
