Only 5mg sodium per serving, chips are crisp.  I sometimes will dip in a low salt ketchup and that adds a bit to the flavor.

Bar Harbor clam chowder is absolutely fantastic!  1. I am not usually a fan of soup out of the can. 2. I am really picky about my clam chowder.  That said, I get this stuff in bulk.  There are several reasons for this, the first of which is the great flavor of clams and potatoes.  Second, I like the fact that the ingredients are all natural and, third, that one can adjust the level of creaminess and viscosity with what one adds to the soup (I like to use a mixture of milk and cream).  The fourth plus is that this soup contains neither bacon nor excessive amounts of spice or pepper - two things that ruin clam chowder for me.  I know bacon is popular with a lot of folks but I really just want to taste the clams when I have a bowl of New England clam chowder.  If you're like me in that respect, then I think you will like this soup too!  p.s. As a child, I was a fan of Friendly's clam chowder (before they changed their recipe).  Bar Harbor is even better!
