With Mr. Big's plans put into a big halt he then decides to convert the Mega Multiplex Food Plaza into a skyscraper. Flo then completes her quest after making enough to decorate Toshiro's Grill and mail the final rent check to Mr. Big who is now down in the dumps with his plans ruined is ready to retire but Flo appears and turns the Big Corp Lounge into Flo's Lounge and turns Mr. Big into her 2nd waiter.

GameplayAs with the original Diner Dash gameplay involves seating customers and guiding Flo around the restaurant to serve customers. If enough money is earned after each level, play progresses to the next. Gameplay centers around catering to customers within a time limit in order to gather as much money as possible. Flo can be moved around the restaurant in order to complete tasks. As customers arrive in the restaurant, the player must drag and drop them onto a table, where they sit down and read menus. Then the player must guide Flo to the table to take their order, which must be taken to the service hatch. After the chef has prepared the meal, Flo must deliver the food. When the customers are finished eating they must be taken a check, at which point the customers leave a tip and their dishes on the table, departing the restaurant. The dishes must be cleared by Flo before the next set of customers can use the table. Each successful action earns the player points, performing the same action multiple times in a row earns the player a chain bonus, which is broken once a different action is performed.
Customers have a series of hearts over their heads that indicate their mood. The longer the customer is forced to wait, the more hearts he or she loses. Each type of customer has different degrees of patience and tipping habits. Flo can perform various actions, such as talking to customers or serving them drinks, in order to revive these hearts. When customers lose all their hearts, they leave the restaurant, costing the player points. The goal of a level is earn a certain number of points. There are also expert point totals for advanced players to achieve.
Like the original, the game has 2 modes: Story Mode, which follows the story of Flo stopping and eventually helping Mr. Big and saving the restaurants of her friends, and Endless Shift, a survival mode where the player must serves an endless stream of customers before losing.
New to Diner Dash 2 is noise disturbance; Cellphone Addicts are constantly talking, and will thus annoy other customers. Families and Joggers don't mind noise, but is a strong dislike to Bookworms yet is a moderate dislike to other customers; the Family's baby is always noisy when unhappy, unless he's in a Highchair (in which case, he's only noisy if the family gets upset waiting for service). Diner Dash 2 adds highchairs for babies, a Mop for cleaning up spilled drinks, a Dessert Bar that customers can browse after eating (only if they have five whole or four and a half hearts), and a Bench (to boost happiness while in line). Back from the first Diner Dash are the Drink Station, Snack Station, and Podium.
Also new is the ability to choose different diner upgrades. As play proceeds, the player is given multiple options for the newest restaurant feature; when presented with a chance to upgrade the counter, for example, the player will be given three options from which to choose (the last is unlockable, which requires an expert score in the previous level in order to attain it).
After the player completes the final level at Toshiro's Grill, the player will unlock the last ten levels at the Flo's Lounge. As the penultimate challenge in Restaurant Rescue, Toshiro's Grill (and Flo's Lounge) are extremely difficult.

Located at the deck of Big Corp, it provides a good view of DinerTown while serving gourmet food.
