This was a great place to go with the parents for Thanksgiving. Dinner was served family style and it was a ton of food! Started with a plate of 3 different bruschetta appetizers that were excellent. Then had a choice of 2 salads, 2 meats - we had turkey that was served with a focaccia dressing and the tilapia served with a side of some of the best creamed spinach I ever had - then 2 side dishes in addition - mashed sweet potatoes and mashed garlic potatoes that were just okay - 2 pasta dishes - we had the signature Rigatoni D and the angel hair with pomodoro sauce/sausage - and 2 desserts!
It is a little pricey, but for the amount of food they serve and all the leftovers, I think it's worth it. The best way to go here is with a group and do the family style menu.
I've been to other Maggiano's in Chicago and to me, they're all pretty much the same - good and plentiful food and fast friendly service.
