I wonder how many chapters this will cover.
What's your number? I say around 15-20.
1 chapter of cooking for each chef with cliff hanger and the outcome in the next.
It be 1 chapter per dish (10 from each opponent and 10 from Owner Bu), 1 chapter per "taste off" and 1 chapter per result/intro to next challenger. But most likely there will be extra content added in between events to set up next arc.
