The Atlantis cafe in The Park hides a register puzzle that blocks a secret basement. Instead of a number code, the register takes four letters, and the answer comes from matching the reserved tables to the drinks on the coffee menu. Solve it and a wall behind the counter slides open.
Quick answer: At the Atlantis register, enter the letters D, B, A, C in that order to open the hidden door.
Where to find the Atlantis cafe in The Park
The cafe sits inside The Park zone and is marked on the map as a yellow Secret location. You reach it during the “Eat the Pizzeria Mold” objective, walking in directly from the street. The register that holds the puzzle is on the main counter, with the two clue notes placed nearby.
The two clues: reservation note and coffee menu
The needed information comes from two sources. On the front counter, the “Table reservations” note gives the regulars’ weekly bookings in this order: Table 1, Table 5, Table 4, then Table 2. Enter that sequence at the register.
The “Coffee menu” poster beside the counter assigns a letter to each drink. A is Espresso, B is Iced Coffee, C is Caramel Latte, and D is The Spiciest Chai. Each reserved table also has a poster showing which drink belongs to it, so you can trace every table back to a single letter.
How the code works
Take the tables in the reservation order, look up the drink sitting on each one, then convert that drink to its menu letter. The result is the four-letter code.
| Order | Table | Drink | Letter |
|---|---|---|---|
| 1st | Table 1 | The Spiciest Chai | D |
| 2nd | Table 5 | Iced Coffee | B |
| 3rd | Table 4 | Espresso | A |
| 4th | Table 2 | Caramel Latte | C |
That gives the code DBAC. The register keypad only offers the buttons A, B, C, and D, so you press them in that exact sequence.
Enter the code at the register
The chime and the opening wall are your confirmation that the code was correct. If nothing happens, the sequence was off, so re-check the reservation order against each table’s drink and try again.
What you get in the basement
Descend the stairs to the storage area. Two collectible notes and one upgrade are waiting there.
- The “Fuck You, Larry Note” on the metal shelving.
- The “Notice Of Decommissioning” note in the back corner.
- The clown-faced Ward-Ice container, which holds Health Upgrade Point 2/3.
Opening the Ward-Ice container triggers the reward pop-up for Health Upgrade Point 2/3. Collecting three of these points raises your maximum health, so this basement covers one of the three you need.
