Been to Delux a couple times on gourmet burger hankering. With a side of fries and a big selection of drafts (and misc comfort desserts/drinks), Delux delivers. There is a cool atmosphere, friendly service, and good food.
One item of note, they advertise Niman Ranch Beef, which many see as grass-fed. Their's is specifically listed as grain fed. So, while the treatment of the animals is still better than typical factory facilities, the diet isn't the same as grass fed. Hey, we can all make our own choices, it just kind of perturbs me to see "vegetarian fed" advertised when it is a non-issue -- grass fed is the standard.
