I don't understand Subway, I walk past one every day and I can honestly say that without exception that whenever anyone is carrying something out, they all smell identical. A couple of guys at work eat them and again, it doesn't matter what they have, they all smell identical. And it's not a nice smell.
For the same money (or less) you can find a decent local sandwich shop and have something made fresh which will be significantly better quality, have the flavour of the product you're actually buying rather than the generic 'subway' flavour and probably be much healthier as well.
