Not knowing whether to wade through the crowd and block a view, I waited near the back. Finally, someone came to take my order. Devil's Kitchen has a select menu featuring burgers and German sausages, fries, wings, and beer. For beer, you have cheap or good. I chose good and asked for something dark. I was forewarned it was the most expensive, but I accepted. It was light, like most German beers I've tried, but had some light spicy notes.
I received the beer and discovered the server's sister lives in Boulder, Colorado. He's visited numerous times for skiing and loves our scenery. Go Colorado!
I received my burger, but screwed something up in the progress. They give you white waxy paper for eating and the chef reached with his metal spatula on which the hamburger lay. I inadvertently touched the spatula trying to help. My future advice- just move the wax paper so it's easier. The only available seat was tucked in the far back corner, a longer reach for him.
