The Milk Bar
It’s open at 10:00 AM for cleaning and at 10:00 PM it’s members only. You’ll get access to this a little later.
The Mayors Residence
From 10:00 AM to 6:00 PM you can enter the Mayor’s Office. Here you can enter the door on the right and speak with the woman inside, the Mayor’s Wife Madame Aroma . She will give you Kafei’s Mask in order to help find her lost son.
The Stock Pot Inn
This area is open all day long, you’ll have to sneak in after 8:30 PM via the second story entrance (accessible via the Deku Flower). You can start a few quests here but none can be completed at this time so it’s best to ignore them.
What you can do is take a letter or Land Title Deed to the first floor restroom at midnight on Day 1 or Day 2. The hand of strange man who lives here pops out, he wants a piece of paper and those items suffice. In exchange you’ll receive Piece of Heart #4 .
The Treasure Chest Shop
Open from 6:00 AM to 10:00 PM, you can run through a randomly generated maze to obtain the treasure chest at the end. 50 Rupees await for Human Link, some Deku Nuts in Deku Scrub form.
There are three chests that refill once you go back in time, they each net 100 Rupees so that’s a quick 300! The easiest one is on the way to the Observatory. Go left through the sewer and into an alcove, bomb the wall here to reveal the chest.
If you get the room key from Anju you can loot the chest in your room at the Stock Pot Inn. Lastly, roll off the ledge near the Milk Bar and onto the Honey and Darling’s sign. Roll from here to the roof of the Shooting Gallery, around the corner is the chest.
