This review is extremely delayed! I went to Greasewood a few months ago with a small group; my friend's Aunt is a long-time bartender here. This is a great place to take out-of-towners looking for a Old West experience.
I noticed "Good for Kids" is marked No, but I saw a lot of families with kids, even though it was a Saturday night. As others have said, the atmosphere here is pretty casual, but fun. Not the place to go for a night of doubachery.
The burgers were solid, they're served with chips, not fries.
Don't curse out loud while inside at the bar, or you might kicked out (seriously)!
