Favorite guilty pleasure foods for all your characters (Yes ALL!) go!
(I am only going to answer for the characters I have put up on the blog! I have too many not yet on here, and this post would never end.)
Shio doesn't understand the concept of "guilty pleasure", but she loves a lot of seafood that is barely cooked - probably not cooked at all, by the standards of most people - a hallmark of her upbringing by the Kojin. She gets some really weird looks.
Gologa usually sticks to very plain, ordinary foods, but will occasionally spend some of his relatively small budget on carbonated ginger drinks.
Ava's another odd one, because she spends a lot of money on fresh fruit that is to her, exotic, pretty regularly - but Ava is essentially immune to shame, including guilt.
Conroy is so anti-culinarily-skilled that he is forbidden from entering kitchens. He really likes meat pies, but they all get eaten by a member of his staff before he gets them. Does that count?
Amis, the latest addition to the Tumblr cast, really enjoys cold foods, but they make her lungs seize up nastily. I think that's pretty close to the concept?
(Not gonna lie, the concept of "guilty pleasure" confuses me sometimes.)
