Currently, I am on my way back to Iowa from Colorado. While we were there we ventured up to the beautiful Rocky Mountain National Park and then stopped in Estes Park for lunch at the Grubsteak Restaurant. There they had quite a selection of meats to choose from for their burgers. Options included beef, turkey, buffalo, elk, and yak. I choose the succulant yak. It was similar to beef, super juicy and delicious. If you have the opportunity to try it I highly recommend it!
