We have eaten at Garden Grill a couple of times, and if your kids like the characters it is a lot of fun. We go simply because it's the best way to see Chip & Dale who are our son's favorites. It never seems super busy, so you get a bit more time with the characters and even multiple visits . It's also fun to see a couple sections of " Living with the Land" from above.
Food is mostly good. The Steak, salad, rolls and fruit cobbler/grunt are all great. The turkey and fish are just OK. It's served family style at your table, so no trips to a buffet. They will bring more of anything you like, just ask.
