Pokémon Sun and Moon/Hau'oli City

Hau'oli City is the game's first big city, home to many interesting sights. It is so large, it is divided into three separate areas: the Beachfront, the Marina and the Shopping District.

The Pokemon Center sells the typical items.

The Shopping District
The Shopping District is where most of the attractions of Hau'oli City are. There is a clothes shop and a hairdresser for character customisation, the City Hall, the police station, and the mall (which isn't accessible yet, you need to defeat Hala). There is also a shop selling malasadas, a special treat of the Alola region. The left clerk sells the Sweet Malasadas for 200 each, which increase a Pokemon's Affection in Refresh, and the right clerk sells Big Malasadas for  350 each, which work similarly to the previous 'regional treat' items, acting as a Full Heal would.

The Mall
This only applies after defeating Hala. The mall has a number of shops:
 * the Gracidea, which is a more expensive fashion shop
 * Antiquities of the Ages, which sells plates and legendary artifacts
 * Move Tutors, which teach Pledge moves and ultimate moves
 * the Battle Buffet.

Marina
There is not much here so far, except the ferry terminal, which has no use.

At the marina is your first encounter with Team Skull.
