I decided to try this place since it's next to the library. I got the tri tip sandwich with all the fixing of grilled onions and provlone with a side of onion rings. The food is A-OK. It's decent not spectacular, typical American diner food. 3 stars for food.
I like the atmosphere and the staff. Black Bear diner has its branding game on point. The thematic country lodge feel is quite homey. The staff were really attentive and friendly.
I'd reckon they're packed for breakfast.
