Diner Dash: Sizzle & Serve is an update and conversion from the popular casual Diner Dash arcade series on the PC. There are 5 new restaurants to work in, with upgrades allowing the player to turn them into the workplace of choice controlling waitress Flo to keep the customers flowing and happy. Also new are wireless multiplayer modes where you can face off against another owner, using one of the new characters on the scene, in a race to keep both stomachs and tills full.
The gameplay is similar to the original but with some adjustments for the PSP console. Players use the D-pad to cycle through different locations and toggle options with the shoulder buttons. The large PSP screen shows the entire field, while scrolling is used on the DS version. This change requires players to think ahead and manage their time effectively.
