Grapevine Mills Mall is one of the best malls that I have been to. There are over 100 stores there and almost all of them are outlet stores. The mall is very nice and is huge. Make sure you have at least a couple of hours to walk around and look. There is also a movie theater and a ice skating rink inside. If you like the food courts from some malls then you will love this food court. There is a huge selection and there is also the great Rain Forest Cafe.
I have gotten many great deals at this mall and my favorite place to go is the Nike Outlet. If you ever go there make sure you have comfortable walking shoes on.
