In this level, you need to prepare all the dishes you have learned in the main game, including dumpling (in case you haven't played Kevin levels up till this point, make dumplings by mixing it first, before steaming)
There are two parts in this level, with increasingly difficult recipes. The first part should have no problem. Don't be afraid of the fire randomly spewing out, but have the extinguisher handy just in case
The second part (after the collapse) is harder, especially with cakes and pancakes. If you're not careful, you may potentially lose an order here
Now, there are ways on how to save time here (not necessarily maximizing tip). For the first part, you can prepare and send by batches of two. Right before the collapse, send one burger first, before sending the next two burgers. The dirty plates will respawn after collapse, so you will have four plates for second part (instead of just two)! For the second part, focus on throwing the ingredients up and down, and through portal. You can also throw utensils through portal to save time. When you are making cakes and pancakes, make the pancakes first, before making cakes. This is because cakes require mixing bowl inside the oven
If you are solo player, all the orders have been predetermined. You just need to practice. I think this level is more worthy to speedrun, rather than just focusing on 4 stars (which is easy even if you lose an order)
