Not really.
GasBuddy has a standard: price per gallon
But this is just a map of the lower-priced items, which are available everywhere. You can find a cheap sandwich, bowl of soup, slice of pizza, or taco virtually anywhere. There is no corresponding standard point of comparison (no "gallon").
It's a little different, instead of maximizing gas/price they're maximizing community rating subject to 10$ limit. I have often wanted to query google reviews in this way. I think yelp might have let you do this back in the day. If this data is already being scraped continuously what I'd really like is a query interface.
There's the calorie. Not always a good metric of health, but it's still a signal.
$/cal varies meaningfully between home cooking, Costco, Chipotle, fast casual, sit-down, frozen meals, etc.
