The cost is low just to go and walk around, but if you buy it's a pretty expensive place.
This is a nice upscale mall, including Nordstrom, Tiffany's, Crate & Barrel, Williams-Sonoma, and other high end chain stores. The fountains are fun to watch - several areas shoot water up in varying heights - you have to watch for a few minutes to see the entire cycle. The walking paths are mostly shaded, although the best views of the fountains are in full sun. There is a nice variety of restaurants and cafes. The Nordstrom Cafe (upstairs inside Nordstrom's) in particular is nice to eat at, with a good selection of sandwiches and salads and a kids menu with good choices. My son had the cheese and fruit plate (2 kinds of cheese, grapes, and strawberries, and crackers). All kids meals come with crayons, juice or milk, and raisins.
This outdoor mall has plenty of wonderful shops and restaurants to enjoy. There is a free-flowing fountain which winds throughout the beautifully landscaped shopping center. I've found many adorable and unique gifts here at a variety of price points. If you want to splurge, there are plenty of places to indulge.
