I love this :D Although you had some mistakes in grammar. Great job!
But hey, we have I, III, IV and V, so where is II?

gah, foodporn is my only weakness

Oh, yes. Blue food! I like your twist on it:)

All your writing is fantastic and it's annoying, dude write a book.

I adore the French Toast one. "You're not trying hard enough" was heartbreaking, and unfortunately realistic. The entire section gave me feelings. :3 And Army Lunch is lovely too, because I could feel Percy's sheer helplessness when faced with the prospect that he may be going insane. I liked Mash too, but that's just a general like rather than a specific one but whatever-

I liked these. They were fun to read. :)

Beautiful job. I love how each chapter has its own theme.

I love this combination. Awesome job! :)

"Miss Gaudrie was just waiting for him to mess up so he could be given yet another recital wasn't she?"- comma after recital
Great job! The bit about insanity was a little sudden at the end, it would've been better if you'd put a few lines about it before the last few paragraphs.

"I'm going to fail both my English paper, mom."- both my English papers
Wonderful job. I love how it's so angsty and fluffy and triumphant in just the right parts. The last line was lovely.

This is an absolutely amazing story, I've never seen anything like it, and it deserves tons of reviews. I adore it.

Your writing of Percy's world is just... flawless. I've never come across anyone who wrote it so skillfully and accurately, and of course, eloquently. As much as I enjoy the series, Rick Riordan's writing style sometimes bothers me. But yours... I'm at a loss for words, it's gorgeous.
Your depiction of Sally made me tear up, you got the mother-son relationship down so beautifully! Your little references, 'Herculean task' were so witty and the entire concept of food as a theme is just genius. Honestly one of the best Percy fics I've read. Gosh, this must have taken some time to write... It's wonderful! Your talent is actually amazing.
