Dine Casual, Enjoy the View

2018 Summer Dates

Opens: April 27, 2018
Closes: October 14, 2018

Winter 2018/2019 Closed

Dine in a casual setting, while enjoying views of what was once the parade ground of the original Fort Yellowstone. It’s also not uncommon to have front row views of grazing elk and bison from the windows of the Mammoth Hotel Dining Room. But the food is also something to look forward to, with our value priced “small plate” options including Bison Sliders, Wild Game Meatballs and Mini Trout Tacos. Breakfast is a la carte or buffet.

In winter, wolf watching is immensely popular. If you’re heading out too early for a hot breakfast, we can set you up with a deli breakfast or deli lunch! You can also relive the day’s adventures with your friends in the quaint lounge located immediately adjacent to the dining room host stand. Open summer and winter.

The Only 4-Star Certified Green Restaurant in the National Parks

In August 2011, the Mammoth Hotel Dining Room became certified by the Green Restaurant Association. The GRA is a national non-profit organization that provides a cost-effective way for restaurants to demonstrate their commitment to environmental sustainability. The Mammoth Dining Room is Xanterra’s first certified green restaurant, and with a 4-Star rating (out of a possible 4-Stars), is the FIRST 4-Star certified restaurant in Wyoming and our National Park System, and one of only 25 in the country. To achieve certification, restaurants must address critical areas that include: Energy, Food, Water, Waste, Disposables, Chemicals and Pollution Reduction, and Furnishings and Building Materials. To achieve it’s 4-Star certification, the Dining Room demonstrated sustainable operations through a major restroom remodel, installation of energy-saving LED lamps and water-saving fixtures, sourcing of local and organic cuisine, recycling and composting restaurant waste, and using environmentally-preferable cleaning products.
