From Kingdom Hearts Wiki: "Agrabah"

The world of Agrabah is basically divided into two parts. The first part is Agrabah itself, where the Sultan's Palace is located. Sora and his party arrive in the Agrabah: Plaza here, where they are confronted by their first enemies in the world. Connecting through a door is Agrabah: Storage, with no enemies and a save point, as well as a few other goodies. Heading north from the Plaza heads to the Agrabah: Main Street; shimmying up the nearby pole will take Sora's group to Aladdin's House and another save point. Continuing north takes them to the Palace Gates, where the massive Pot Centipede battle begins. Heading west from Main Street sends them into the Agrabah: Alley, while entering the high entrance to the east goes into the Agrabah: Bazaar. These areas interconnect on many levels, both high and low.
