No such thing as a free lunch, but how cheap can you get one?

To Guelph last week to visit my daughter who's a music student at U of G. I ask her, " where's the cheapest place on campus for lunch?" She suggests we go to the Grad Pub.
Pictured here is what we got: a veggie samosa with tamarind dip, basmati rice and vegetables with pineapple juice for her; a veggie wrap and large mug of cranberry tea for me.
Total cost? $6.88 for two lunches. This is the one to beat.
