Are you totally averse to balloon tires? The Schwalbe Big Apple provides that fat tire look, but without the knobbies. More importantly, it's a nice cushioned ride for casual touring. I had Specialized Nimbus 1.5" slicks on my mountain bike for a long time and also hated the wimpy look of them. The 2.35" Big Apples look like motorcycle tires compared to them and make me feel like the macho man I am.
