If you want food thats worse than chef boyardee's, then by all means stick with Tony's.
They have the worst food i've ever tried in my whole life. I tried my son's meatball and couldnt swallow it. It was bad. My chicken parm was nasty. I'd stay away from anything with tomato sauce in it to be honest, if you must go.
Crystal Palace has MUCH better food!!! the environment is so much nicer too. i find tony's very cold....not literally, just the atmosphere is cold and bland. Besides the statue of lady/tramp, there's nothing unique or nice about their atmosphere.
I think your kids would have fun at crystal palace. Characters are awesome, and the food is pretty good. They have a carving station, great meat selections, their mashed potato is so good, they have a kids section with typical fare such as mac/cheese, chicken breast nuggets (not the processed kind), great salad bar, and the desserts are incredible. Wonderful selection of tarts, fruits, even icecream!
If anything, as the OP said, i would go to liberty tree tavern. GREAT lunch menu!! And they have family style, all you can eat, at dinner time. Both are great! You cant go wrong with this place either.
