Nice game. I enjoy these types of games a lot so I can see myself playing a full version of this down the road :) I quite like the dialogues as well.
I feel there are a lot of tedious part in the game right now, like how you have to walk into the back room to buy ingredients or check the recipes, and the pace of the movement is slow compared to the space of restaurant. I'm sure those could be easily improved upon though.
Good job on submitting your game!
