Here's a walkthrough of the entire game on Gamezebo:

The Delicious games are somewhat like Diner Dash games, a time management game and are really fun. A girl named Emily goes from restaurant to restaurant, with different scenarios in the different games in the series.  You don't seat the people as in Diner Dash.  A bubble appears over their head with their order, and you deliver the food, they come to the counter to pay, and you clean the tables, plus some people come to the counter for take-out orders.
 
I hope you enjoy this series of games.  They're really fun.
