I drive a long way to have the Colorado burger I am a chef and it is by far the most delicious burger I’ve ever had. I love the smash fries as well. The service from the manager Jack is impeccable. He makes sure the burger is perfect every time. I see a poster that says the Colorado is only available for a limited time. That would be a huge mistake. I’m sure the other burgers are very good, but the Colorado is a home run! I’ll keep coming as long as it’s available.
