We plan to pack a lunch sometimes when we visit Yellowstone, but we decided yesterday to eat a the dining room of the Roosevelt Lodge. It was Great!
Jeff had a bison burger and declared it wonderful. Less fatty than most beef and with a nice taste. I had smoked trout on baguette slices (really an appetizer) and it was also really good.
If you visit Yellowstone, we both recommend you eat there for either a lunch or a dinner. Here’s their website: http://www.yellowstonenationalparklodges.com/roosevelt-lodge-dining-room-7198.html
