Neighborhood Eatery Happy Hour: Cocktails & Small Plates 4

Restaurant storefront in Yellowstone National Park with white facade, large windows, and outdoor seating.

The Mammoth Dining Room serves American fare built on sustainable, local ingredients. The bison brats deliver a plump bite with crispy skin and grilled onions, while the bison sliders and wild game meatballs snap with savory notes. Pistachio-Parmesan Trout adds Montana flavor, with gluten-free pasta and buns available on request. Sitting in the Mammoth Hotel, the mirrors from 1883 National Hotel add a quiet, historical mood as elk and bison roam the parade grounds outside.
