Best Mushroom Bison Burger [Devils Tower WY] Right before you enter the Devils Tower Monument and just across the DT Trading Post is this cafe... plenty of seating inside. This is a counter service so we placed our orders at the counter then they brought us our food to the table. I ordered the Mushroom Bison Burger (lettuce, tomato, onion and pickles on the side) and it was deee-licious! The meat was tender, juicy and flavorful. Bison is naturally leaner than ground beef too! The only thing that bothered me a little was the amount of flies inside the restaurant. Other than that I was enjoying my bison mushroom burger. Lots of parking on a paved parking lot. From the parking lot we walked up to the Devils Tower National Monument sign and took some photos with the rock in the background. Review #3488 read more
