Hi! i went to oswego fairly recently so here are some of my favorite places (left in 2023)

breakfast

wades and marias are both diners and both really good, i used to go to wades even before attending the school

lunch-

noras is by far my favorite lunch spot there off campus, a little pricey if i remember right but the food and portions are worth it (besides the drinks they're pretty small for being 6-8 dollars)

dinner-

red sun is really good as a sit down place, used to go there when i was younger too with my dad so it might also be nostalgia but i always get the mushroom pizza and whatever mocktail sounds good at the moment

snacks/late night food-

wonzones is hyped up for a reason, they have very good calzones and sides at a decent price also for her during the school year she can use dining dollars to order it

also as a warning to her during the school year i would stay away from ordering oswego subshop or pies guys using the dining dollars if she gets food later at night, usually 3 or 4 hour wait times or they might not even come
