I agree..you left us with little info

What park will you be in and what meals will you be eating?
Whenever we have to pay for food at Disney out of pocket we like to eat at a regular place for lunch (like Pecos Bills, Cosmic Rays..you know) and then maybe a nicer Counter Service for dinner like Columbia Harbor House, Earl of Sandwich, Cantina de San Angel, Tangerine Cafe, Wolfgang Puck Express. OR..what we like to do is use our out of pocket day to "eat around the world". We'll buy small things from every (or almost every) country in Epcot and snack all day. We usually end up stuffed (and tipsy) by the time we get to Mexico and are very happy! And between the both of us we've usually only spent $50-60.
