We first ate at Sir Scott's Oasis in Manhattan, Montana a number of years ago. Back then, it was excellent, so we couldn't wait to try it again on our 2011 Christmas trip to nearby Bozeman. We searched for reviews and read some good critiques, but some less than auspicious. Several referenced surly service and brown gravy served on top of prime rib. That should have stopped us, but we gave it a try anyway. What a mistake it turned out to be. We were half-heartedly welcomed by a waitress that said the prime rib was the special. Leary of the reported brown gravy, I inquired and was told it was served "au jus." Knowing that au jus means "served in the natural juices that flow from the meat as it cooks", my fear disappeared. I asked the waitress what beers they had on tap and was told "cold." Thinking it was her little joke, I waited in vain for her to list the beers. I guess it is a secret that can only be unraveled by approaching the bar and reading the tap handles. We opted for Mojo potatoes to accompany the prime rib.....When the rib arrived, you guessed it, a lake of ugly brown gravy engulfed the meat. "Disgusting" is the best description I can think of to describe prime rib smothered in greasy, nasty gravy. To top off the lovely culinary experience, the Mojo potatoes tasted like salt encrusted little chunks of desert. I never knew potatoes could be that bad. Awful service and awful food. A slam dunk.....I later met a Bozeman native that told us the food used to be good but had gone significantly downhill. Wish I had inquired locally before we wasted our money.
