Is there such a thing as an app that calculates the calories in restaurant menu meals. I am on a diet and don't want to be anti social so going to a Smith and Western with family today. I have looked at the menu and cant work out the calories, I tried googling but nothing came up, just wondered if there was such an app, alternatively does anyone know if the chilli and rice meal would be lower than the Cajun chicken with coleslaw meal? I am trying for under 500 calories.
