This is recommended to be done on a fresh save file after completing the game for the first time

The target goal is to have 2000 coins after opening the restaurant for the first time. Iberico will appear on the morning after opening the restaurant regardless of what day the restaurant is opened. This guide will contain a list of what ingredients and materials to prioritize when running through the dungeon.

• Most Important: Do not open the restaurant on the first day. Alder will be unavailable to buy furniture and one table and chair is not sufficient to reach the goal.
  
  
• Play in easy mode to progress as far as possible.
  
  
• Skipping the first day will allow for two runs through the dungeon. Technically you can go as many times as needed if you do not open the restaurant, but as long as you're making it to floor 3+ each dungeon you should have everything you need after two runs.
  
  
• Although the Long Wood Table is more material efficient, it costs more coins per seat to produce. (3:4 Ratio)
  
  
• The Minimum amount of seats is 5 for the Lunch and Dinner rush. 1 chair and 1 table are provided by default. For the rest, 70 Wood is Required (3 stacks).
  
  
• Do not buy any other work tables as you will not be able to place them. Use only the starter pot.
  
  
• Defeating the Black Rooster and Mother Hen can drop higher tier ingredients, such as Tentacle and Fish.
  
  
• Customers will only order what is available. Discarding lower value ingredients will force customers to order food with higher values.

Below is a list of all possible ingredients obtainable in Green Ruins and their respective values.

Ingredients should be discarded in the order of their value. Even if you do not have a full inventory of valuable ingredients, having lower value ingredients in the fridge will prevent customers from ordering higher value meals.

* Drops from Arena and Boss Chests

After two days of prep there is one last thing to do. In order to have enough tables and chairs we need a base amount of money.

After completing Biscotti's initial quest line, you will have 200 coins to work with. However, that will not be enough to gain enough tables and chairs to survive the two rushes.

The solution: Open the restaurant, serve one customer, and immediately close the restaurant again. This will complete the Back in Business! quest and reward you with 350 additional coins.

In Total this will be 550 coins, enough to buy the 4 tables and stools required. Place the stools and tables and open the restaurant for the full day this time.

On my first attempt I net 5,000 coins, well above the 2000 threshold.
