• Bottle of Coke (unopened, stored without exposition to light) --> one year after exp. date
• Can of noodle soup (unopened) --> one year after exp. date
• dried noodles (unopened; the ones you have to cook before they are edible) --> unknown - at least one year after exp. date
• soft candy (unopened, but exposed to higher temperatures) --> 6 months after exp. date
• chocolate (unopened) --> 6 months after exp. date
• yoghurt (unopened, uninterrupted cooling chain) --> 2 weeks after exp. date

all of these food items were perfectly edible. The candy was a little bit less soft, as it was exposed to higher temperatures once, but they tasted as good as freshly bought.

Most things that have not been opened and/or have not been exposed to light or temperature extremes can be eaten safely way after the expiration date exceeded. But with dairy one has to be more cautios. A week or two past the expiration date shouldn't be a problem, considering it has never been opened before and the cooliing chain has not been interrupted.

I wouldn't risk meat or fish, tho. Food poisoning can be a nasty ordeal. I'd rather dispose of it than taking any risks.
