Columbia Harbor house is lunch only,I think....but we love it there.... cheap? I assume you mean disney cheap,since nothing is cheap there.....

Try Cosmic Rays,they have a variety of choices, frankly I don't much like MK food qs, I'd leave,and monorail over to the contemperary and eat in their qs cafe-then head back..... that's what we usually do, less 'good' food choices at MK than other parks IMHO
