Neither my husband or I can have any gluten, dairy, eggs or soy. So airport food for us normally means bags of chips or stale trail mix and bottled water. What a surprise to find a restaurant with a gluten-free menu and staff who are knowledgeable and helpful regarding dietary restrictions!
Don't let the fact that is a smoking lounge deter you - there is a non-smoking section outside the lounge, which is actually quieter than the interior area. The non-smoking section is kind of small, but we only to wait 10 minutes for a table. Our food arrived quickly, and other than the corn tortillas being on the dry side, it was pretty good for airport food. Including tip, we both left with full tummies for under $20, which is pretty reasonable compared to the prices at most airport restaurants.
So if you are connecting through Denver and have time for a meal, check this place out! You wont' regret it, as long as you keep in mind that This Is An Airport - so you won't get 5 star quality food or cheap prices. But at least you can sit down and eat something safe and relatively healthy. :)
