I gave it a go, clearly with my carpal tunnel syndrome I'm not the target audience for this 😅 I did a bit better playing on a touchpad - perhaps this could work well on touch devices? Then I played a little with only RMB (queued actions) and liked it a bit more (more precision/prioritising, less frantic clicking), but still the pace was too fast for me. I think I'd prefer most actions to take longer - I felt a brief relief only when washing dishes or making trips to deliver food.
As for gameplay, I always died before I could make a hamburger, so I felt there was little variety. I think I'd prefer to start with 2 recipes with some ingredient overlap.
Also in the early game I feel that there is little decision making or possibilities for optimisation - I suppose it changes when buying more equipment/recipes but I did not get that far.
