You have probably seen us, heard of us, might have even confused us, but what is Illegal Burger? Read along to learn our story and the man behind it.




The Basics

Illegal Burger is a quick-casual burger joint with a full-service bar centered around a prison theme. We focus on customer service and high-quality food. We value fresh produce; thus, our patties are made with fresh, all natural, never frozen, no antibiotics or growth hormones beef. But it does not stop there. We know everyone has different preferences, so we offer veggie patties, turkey patties, grilled chicken breast, and codfish as well. Each burger is accompanied by a fresh baked bun from a local bakery, Aspen Bakery. Pick from a fluffy soft brioche bun, pretzel bun, or whole wheat bun. And yes, we offer gluten free buns and lettuce wraps! Each burger is topped with the freshest ingredients available. We have an incredible selection when it comes to fries and sides. From thin-cut fries, waffle fries, to our hand crafted Cheesy Taters. There is more than just delicious food at every Illegal Burger. Our full-service bar includes refreshing margaritas, local beers, and even alcoholic shakes served in fun mason jars. Don’t just take my word for it, make sure to check it out!
