English is a beautiful language. Cheap can mean either 1) low cost, and 2) low in quality. In this case, we have both forms. Dollar cheese slices, $5 gyro, $3.50 (not so) small poutine. Good deal? Well not if the food is gross.
Meat lovers pizza had fake bacon on it, and although hot, just had no taste. As for the poutine, fries were "mccaine", gravy was chemical orange, and the cheese was a mix of half-frozen curds and shredded mozzarella. Barely passable.
On a budget, or late night after a night of drinking, it'll do. Just expect cheap both ways.
