RemindMeNot2 is the iPhone App that allows you to record bad or good experiences that you have in a restaurant in order to not make the same mistake again. Has it ever happened to you that you have gone to a restaurant, ordered a dish, eaten it and been incredibly disappointed with the dish, only to realize after that you have been to this restaurant before, ordered the same exact dish and had the same disappointing experience?
