At least during the early stages of the game, most players ofPersona 3 Reloadwill spend their days making social connections and their nightsboosting their social stats. The restaurants of the Iwatodai Strip Mall are especially good for these boosts, since each one boosts a social stat by more than a normal activity like studying at home.
However, each of the three main restaurants also has a second menu item that’s only available on certain days of the week. They cost more, but they also boost yourPersona 3 Reloadsocial stats by a larger amount. The only issue is that you’ll need to meet some requirements if you want to purchase these meals.

How to Unlock Seafood Full Course and the Special Hagakure Bowl
The Wakatsu Kitchen’s Seafood Full Course is available onMonday, Thursday, Friday, and Sundaywhile the Special Hagakure Bowl at Hagakure Ramen is for sale onTuesday, Wednesday, and Friday. When you first enter one of these establishments on one of these days, the game will tell you that this special menu item is available.
However, you won’t be able to buy either of these meals, at least not at first. This is because you need to reach a certain rating in a social skill first. To buy the Seafood Full Course, you need to reach rank 3 of Charm (Confident), and to buy the Special Hagakure Bowlyou need to reach rank 3 of Courage (Determined). Once your stats are high enough, the next time you enter the restaurant on the right day you’ll have no trouble buying the better option.

Of course, you also need enough money to pay for the meal. The Seafood Full Course costs 900 yen, and the Special Hagakure Bowl costs 1,200 yen.
How to Unlock the Weekend Wilduck Set
You don’t need your Academics at 3 to get the Weekend Wilduck Set. Instead, you’ll need to unlock Elizabeth’s quests and complete a specific challenge.
The quest in question is 11, “Please prevail in the Big Eater Challenge.” To even access this quest, you’ll need to complete three others:

With all that done, you’re able to attempt the Big Eater Challenge. After you accept this quest, you should be able to visit Wilduck every night and pay 1,800 yen to take on the challenge.
Unlike the eating challenges in otherPersonagames,you don’t need high statsto beat the Big Eater Challenge. Instead, you need to choose the right options:
If you choose the wrong option, you’ll get the same Courage boost you would have gotten from eating a Mystery Burger. If you succeed,you’ll get a big boost to all three social stats, complete Elizabeth’s quest, and get access to the Weekend Wilduck Set. Like the name suggests, the set is available onSaturdays and Sundays, and it only costs 1,200 yen.
