Hat tip to @calam1ty, here is the 2Good2Go app. There is a rating to suggest whether the grab bag of extras is good value at various restaurants and grocery stores.
I plan to try some indie coffee shop offerings some time.
I expect some of the produce offerings would be quite ripe.
I was surprised to see Eataly and Summerhill Market have offers, as well as Tre Mari, from time to time.
