I've eaten here a few times and although its located in the middle of downtown Crestline it doesn't seem like they are trying to hard to impress with their service or food quality.
I've gone there mostly during the week when it's slow and it almost seems like the serer really doesn't want to be there. The last visit I had she never even came back to see how things were going and simply dropped off the check when she brought the food. The food quality is ok, probably on par with Denny's. The prices are a bit high for the kind of food you get.
Overall there are much better places to dine in Crestline.
