This launched a few days ago on Steam Early Access, although it seems pretty well developed already, barring some of the item descriptions and a truck customization system still to come, along with new territories.
It already has voice acting and the soundtrack is complete.
Big differences between this and Cook! Serve! Delicious! 2!!! is that in this one you are running a food truck - this means rather than having waves of rush hour followed by slow periods, instead you do a ton of prep in between stops, with a few advance orders on the road.
They've also completely removed chores (such as dishwashing and taking out rubbish) which makes for a much more fun game.
They also have added a proper campaign mode, with a campaign map and location-based progression.
Last big change is being able to flick the right stick to serve all your ready dishes at once, which is great.
Here is the launch trailer:
They have also been very open with the Early Access updates, here:
If you liked the first two, this is brilliant.
It'll be great on Switch in Summer too.
