High-Quality, Quick-Service Food With Soul

Straight From Chicago’s Neighborhoods to Yours

For more than 40 years, diners in Denver and Boulder have come to Mustard’s Last Stand when they want fast food’s ultimate creation — the Chicago-style hot dog.

We’ve got that and more: addictive hand-cut fries, Polish sausages and more than a handful of sandwiches, including our legendary Italian beef. Are you looking for vegetarian or gluten-free options? We’ve got plenty of those too. Come by, have a bite and say hello!

We can also bring the taste of Chicago to you. Let us cater your next event!
