I spent so much time in Denver back in my rocket scientist days testing Space Station components at the Martin plant at Littleton and when we had a night off we would head to Bennetts BBQ out on Arapaho.
It is indeed one of the best BBQ places that I have ever been to. Their steaks are good too. Great place!
Their location in Colorado Springs is good too, I was there on business and was happy to see they had a restaurant there too and wouldnt have to drive up to Denver.
I dont remember unfortunately what the sauce tastes like but everything is good there. I do see that they sell their sauce in the bottle but alas do not mail it. I will have to see if they would be so kind as to ship me a bottle or 2.
