After taking down the Hell House in the Colosseum, and while Aerith is getting a makeover with Madam M, Cloud can take on a series of sidequests given to him by Chocobo Sam in Chapter 9 of Final Fantasy VII Remake.
NOTE: Which sidequests you receive in Wall Market depend on which answers you provide to certain people. You will either receive The Party Never Stops and Dynamite Body, OR you will get The Price of Thievery and Shears' Counterattack.
In order to unlock the Best in the Business trophy, you will need to replay this chapter once you unlock Chapter Select after completing the game once.
Here are the choices you should make in order to access this sidequest:

- At Madam M's, pick the cheapest massage Poor Man’s Course – 100G
- When Aerith asks how you like her outfit, reply It’s alright.
- Complete The Underground Colosseum main story quest.
Other choices have been known to produce the same results, but this is broadly what must happen in order for you to unlock this quest.
The Party Never Stops
Start by going to the Clothing Store owner’s son. He will direct you to his father, sprawled on a counter in the bar across the street.
Go to the Materia Store, on the other side of the city. He will ask you to go to the Inn to buy the sauce from the vending machine.
It seems that the chances of getting the sauce depend on the number of enemies you have analyzed with the Assess Materia. We had 55, which was close to the maximum possible at the time, and we obtained the item on the third attempt. It seems this is a scripted event. Take the sauce back to the Materia Store.
Now, head for the bar. The Clothing Store owner asks you to determine what's causing problems in his kitchen. You have three possible choices here — choose the one that corresponds to the Magic Materia you possess of the highest level (the Stove for Fire Materia, the Fridge for Ice Materia and Power Supply for Lightning Materia).
The quality of the reward will depend on the level, with a Moogle Medal at best.
After eating, Johnny becomes sick. Go to the Pharmacy and talk to the owner, who will ask you to deliver medicine to sick people.
You can ask the pharmacist for some hints to find the sick people. The can be founf here:
- In the toilet of the bar, where you met the Clothing Store owner.
- At the end of the long alley north of the Gym.
- At the bottom right of the alley near the entrance to Wall Market, hidden in a corner.
Go back and talk to the pharmacist, who will give you the VIP Card. Deliver it to the Clothing Store owner, then talk to his son for your reward.
This will unlock the final sidequest in this chapter.
