I'm not certain. They do have a large variety of bagels so there's a good chance they do. They are very friendly and customer oriented so I'm sure they would welcome a phone call to ask them.
I don't see salt bagels. Here is the menu. Enjoy. http://www.blueridgebagels.com/breakfast-menu.html
Can't say as I always get their "everything" bagel, but I would think that they would.
