I have only 6-10 proper Nashville hot chicken restaurant experiences and this is as good or better than others I have had.
1st time eating here was with some buddies in the middle of the pandemic, this review is for the 2nd visit a year later.
The daughter and I went there recently while the wife had appointments at the university.
Loooong line (30+ minutes just to place an order) and they didn't seem to be short-staffed... but the front of house fella was certainly hustling. We waited outside with our iced tea and beers while our food was prepped. Deviled eggs were okay but expensive. I had a mixed 2x piece meal with greens and grits (everything was awesome). The hot chicken was a bit much for me, but that is no fault of the restaurant, instead my Scottish heritage. The daughter is gluten-free and she had a pulled chicken sandwich on a GF bun with fries. She says both were good and I can confirm the fries were tasty and crispy.
Overall, I can appreciate the chicken, very juicy, crispy and very tasty; but dang did it wound me later on. ;-)
Roost is considered a must-stop in all our future trips to/through Bozeman, but I will probably call in my order next time.
