Located near Aeon's Makuhari corporate offices, this massive shopping complex contains some 350 retails shops and restaurants, along with movie theaters and sports facilities. It's made up of four separate parts - the main mall (which includes a large restaurant zone) and separate malls for sports, children, and pets.
In addition to the expected dog-grooming services, the pet mall also offers a hydrotherapy studio for dogs, and a surprisingly wide range of canine gourmet foods. You'll find frozen dinners, various flavors of ice cream, cakes and pastries, and a full-on deli counter devoted to dogs. They even sell (non-alcoholic) beer and wine for discerning pets.
Back in the main mall, the food-court section is a bit nicer than average - you can pick and choose from the various stands, get a glass of Spanish or Italian wine, and sit by the windows looking out onto the placid Makuhari landscape.
