This is the worst steak and shake I have ever been to. The food took 20 minutes from the time we ordered and the food was cold when we got it, the fries were on the border of stale and cardboard and unsalted. They forgot my buddies milkshake which took another 5 minutes to get. This place is a joke.
This is some of the best authentic Mexican food in the state (especially the tacos). My girlfriend and I have been coming regularly for months and have always had great service. Our favorite server Julian is always so welcoming and prompt with his service, and he's just a great guy all around. If you live in the Denver or surrounding areas you HAVE to eat at 3 portrillos.
I have a PhD in world religion. I spent 6 years at cambridge studying geographical references from religious texts. I spent 4 years in Egypt with a group of geologists excavating sites at the pyramids and various other sites in the middle east. I'm also one of a large handful that have had access to the Vatican archive. That's pursuing your education smartass.
