Great food and Drink are the norm at Denver International Airport
DIA serves up some great food. The restaurants at DIA are diverse, and you don't even have to go through security to visit the best of them. These eating options make fundamentally feasible, lunch meetings, dinner meetings, and a drink with a client both possible, comfortable, and something worth doing.
The main terminal has by far and away the highest quality food in the airport. Pour La France, a copy of a Boulder Colorado favorite, and the Buffalo Grill, with another location Downtown Dener are both reasonable places to eat. Meeting a client here is not only a good idea, it allows you to serve them a high quality meal too. On the lighter side, the ice cream shop on the southwest side is pretty good, there are a number of coffee shops, and a line of fast food offerings.
Should you and your colleague be flying through DIA at the same time, You are privvy to an expanded menu. There are many other food courts located throughout the airport.The list below is of some of my favorites.
I expect to hear some suggestions through the contact form, located here. However, my favorite pizza, on the run, in the Airport, is on Concorse C, and is called Villa Pizza, located right next to McDonalds. You can get lots of Italian food for your trip that is worthy of the weight to get onboard your aircraft.
