It's too bad that this and the next chapter are just filler between dark cooking society battles, because by itself, this chapter is pretty funny. The disguises from Mao and Shirou, the posturing from Mao, and the twist at the end are all great.
The beginning of the chapter's a little confusing, but it's not hard to imagine what happened. Mei Li realized that they had run out of travel funds, told everyone to make some, Mao and Shirou heard of this opportunity and went to one restaurant, Fei had the same idea, but went to the other restaurant. Hijinks ensue.
