I love Maggiano's!! It is great for big parties. My family and I are a huge fan of the Family Style Lunch.

You get two choices of appetizers, salads, pastas, entrees and desserts. They also refill the plates. So if you finish your appetizer, they'll give you another one and if you don't finish it they let you box it up.
My favorites are the Calamari Fritte, Stuffed Mushrooms and the Tiramisu!!!
Everyone in the world needs to celebrate one event in their life at Maggiano's. It is totally worth the price.
