Lowering the quality of your product is the first step to failure, IMHO. We raised our vending prices this year and still did fairly well. but the numbers were down. Crowd attendance numbers were down at most of the events, so I know it wasn't just us. Happily, at some of our repeat events we had several customers who said they look for us now when the event comes along. Lower quality food would probably not bring back those customers.
