Had lunch there yesterday. Just as lovely as dinner was a couple weeks ago. No valet parking at lunch time. Had a wonderful salad platter topped with a good amount of shrimp salad (options were chicken salad or tuna salad)I choose the blue cheese dressing - it was great on on the sweet side, and a cup of chicken wild rice soup.
As for BRUNCH: they only hold it like on Mother's Day, Easter, etc. and by reservation. They are open for breakfast Saturdays & Sundays 8 am to 11 am then the lunch menu starts. I'll give it a try and let you know how it is.
BTW where the pro shop was next to the dining rooms they are converting it into another dining room so they must be doing good.
