I love (nearly) anything sweet so I would much rather sneak in some caramel popcorn from Kernels than to have plain ol' butter popcorn at the movie theatre. (Not that any of us would ever sneak in outside food to the movies....)
Plus, they always seem to have some sort of deal -- buy 2, get the 3rd free, or buy 1, get the 2nd at half off -- that it's just so hard to resist!
Can do the usual bag sizes, but they have a few larger options in tins (similar to the sizes found in pharmaprix during the holidays) that make good gifts/snacks at a party.
And, if you really must... You can google the company and see the nutritional information online. Surprisingly not as bad for you as you may think!
