I would also like to add to my previous comment, about maybe adding prestige upgrades for washing dishes, or maybe have lucky dishes where its a small chance but if you get one you get 1000x money for cleaning it or something? Maybe expand the menu to include vegetable dishes aswell!
Personally, i think something should be done with the dishwashing, so it can be used throughout the game, not just at the start. I also think it slows down a little too quick, as at the moment it is at the point where i am generally forgetting about the game because i can only cook once or twice a day! Having an option to automatically move the dishes would be nice, as well as dips maybe? I think it is heavily relying on people buying gems towards the ends, and in the middle there was a blank spot where progress was really slow (might have been my dish choices though). I thin this game is good but there are a few things that are missing or need tweaking in my opinion
