HMM well he loves sweet stuff, hates sour & bitter things, and he doesn't really care about eating healthy at all (he is a creature of whim) so i'm gonna say his top 5 would be like...

1. strawberry (he really likes anything with strawberries, ik that's his favorite food for sure)
2. parfait
3. barbecue... any meat-exclusive thing in general actually since he's kind of carnivorous. would eat his steaks bloody if he could afford them
4. burger. he'd be a big burgerhead i think but he doesn't get to eat them much. he'd take any lettuce or other leafy stuff off, though.
5. any kind of assorted box of chocolates (won't eat the dark chocolate, though. you eat them). he thinks they're fun. his favorites would be the ones with fruit ganache in them
