I have to vote for Wolfgang Puck Cafe. On our recent trip (we just got home on Sunday), we ate at both WPC and Spoodles. I may be in the minority here, but we really didn't like Spoodles. I thought the food was very bland (we had the 4 cheese flatbread appetizer and the steak with fries for entree - no dessert).
On the other hand, Wolfgang Puck was outstanding! I had the spinach & artichoke dip appetizers (this was SOOOO good) and the steak with fries and onion petals on it and some sauce that was really good! I also had the cheesecake for dessert, which was outstanding.
Wolfgang Puck is a beautiful restaurant. It was much noiser than Spoodles, which was very quiet and seemed more "fancy" to me. "With kids, I think Wolfgang Puck is more kid-friendly. Plus, our friends went and said the kids mac & cheese is the best they've ever tasted!
Just my humble opinion.
