We just got back Wednesday and did Garden Grill, Le Cellier, the UK Fish and Chips take out. We loved them all. But I think with young children, I would definitely choose Garden Grill. As others have said, the character interaction was great (Dale actually mixed and served our salad!), and family style is a plus if the kids are a little picky. Also, the scenery keeps changing to keep them interested. The Fish and Chips at UK was excellent, but our favorite (Me, DH, DD20 and DS15) was Le Cellier - absolutely wonderful. DS had the cheddar cheese soup for appetizer, then had the NY strip steak and another cheese soup for dessert!
We wanted to do Biergarten, but so much to do, too little time! We'll just have to plan another trip!
