The Goldenrod Department Store is a store found in the Johto region. It is located in Goldenrod City, and is the largest department store in Johto. Unlike regular Poké Marts, this store houses many items and many floors.
The fourth floor contains medicinal items that permanently enhance a Pokémon's stats. The items appear the same in both Generation II and Generation IV.
The fifth floor is dedicated to selling TMs. A young girl can be found on this floor, talking to her will unlock the option of a Mystery Gift. Additionally, there is a man willing to trade a Drowzee for a Machop.
The sixth floor contains a picnic table and some vending machines. In Generation II this floor is titled the Rooftop Square and in Generation IV it is titled the Tranquil Square. In addition to the vending machines, there is a raffle exclusive to Generation IV. It can be entered for 300, there is the chance to win a Berry, a Poké Ball, or a select TM. In HeartGold and SoulSilver this is the final floor; in Pokémon Crystal there is a flight of stairs leading up to the topmost floor. Whitney, the gym leader, will be up here around noon on Saturdays, and you will be able to add her to the PokéGear if you come here at the right time.
The rooftop is a floor exclusive to Pokémon Crystal. The player must travel the final flight of stairs as the floor cannot be accessed through the elevator. There are binoculars that lets characters see things in the distance, many people go up to the rooftop to take a break from shopping. There are some vending machines selling Pokémon dolls. The player is not able to buy from the vending machine as there are no dolls left. However, there is an occasional Rooftop Sale which Camper Todd from the Pokégear will call about.
The basement is the bottommost floor of the Goldenrod Department Store. It is only accessible by the elevator and has no items up for purchase. A team of works and a Machoke inhabit this floor and are moving boxes around. In HeartGold and SoulSilver, talking to a worker will cause each Machoke to move a box, allowing one of the blocked rooms to be accessed.
