My entire family loves Applebees. We all order just about the same thing every time - not for lack of choices tho!! I have a picker eater, and this is one of the ONLY restaurants she really enjoys! If you are a drinker, they offer a ton of nice flavored drinks both with and without alcohol.
My family enjoys the appetizer sampler, which can be eaten as a meal by one person. I love the veggie pizza and also the chicken salad- both are amazing. As far as the kids menu, it is pretty normal - free refill, etc - but no dessert.
Customer service is usually great, but you can have a bad server anywhere you go. The kids can get a free balloon, but you usually have to ask.
