In Penguin Diner 2, players take on the role of a penguin named Penny who is running her own restaurant. The goal of the game is to serve customers and earn as much money as possible in a set amount of time. The game is divided into different levels, each with its own set of challenges and goals.
At the start of each level, players must seat their customers at available tables. As customers arrive, they will indicate what they want to order by hovering over their heads with speech bubbles. Players must then click on the customer to take their order and deliver it to the kitchen.
Once the order is prepared, players must take the food to the correct table and serve it to the customer. If the customer is happy with their meal, they will leave a tip. Players must also keep an eye on the restaurant's cleanliness and make sure that tables are cleared and cleaned promptly.
As players progress through the game, they will unlock new menu items, restaurant upgrades, and power-ups to help them manage the restaurant more efficiently. The game becomes increasingly challenging as players must serve more customers, manage multiple tables, and deal with demanding customers.
