Earlier this summer we stopped into Salt Lake City for a couple of hours, and I made sure we got a bite to eat at Tony Caputo's. They have the best deli sandwiches. We always ask for their hot mustard on the sandwich and on the side for dipping. This mustard is so good that in the past I've asked them to squirt some in a jar for me so I can bring it home. Now they've expanded their little deli into a market and their yummy hot mustard can be bought.
