Great and Unique!
The whole diner thing has been done to death, but at least this has a unique spin on it. The game seems to run well and its really fun too!
Only thing is you could have made some sort of upgrade system, you know for the kitchen or chef. You could have had the cafeteria be upgradeable by buying more tables, food, ect.
But regardless, still a great game and a joy to play, well done!
