This level is fairly easy to obtain 4 stars, and is the first video I ever recorded for Overcooked 2 gameplay. You will need to serve at least 12 dishes to obtain 4 stars. I have experimented few methods here, including serving batches by 2 (as shown in the video), 3 and random. Based on how I play, serving batches of 2 is the easiest way to get 4 stars. Definitely not a way you will seek though, if you are shooting for world-record.
Here's how it works: One chef cuts the ingredients, while the other moves around and throws ingredients to the cutting chef. For the first batch, this moving chef also cooks rice. If this moving chef washes the dishes, the cutting chef should cook the rice instead.
I have also shown slight imperfections, indicating that you should be able to do it as long as you don't make too many or severe mistakes. If you have time, you can also cook another rice and serve third dish for the last batch, so you will serve a total dishes of 13 instead of 12.
The first four dishes are fixed, so you can proceed with throwing 2 cucumbers and 2 fish to the cutting chef. The rest will be randomized. This only applies for solo players, not multiplayers.
Hope you enjoy the video! Stay tuned for more videos.
