I've eaten here a few times. Their happy hour menu is really good, particularly the mussels and crab cakes. And their mixed drinks are quite good. I would call it an extremely good value during happy hour. And, the service has always been really good.
The views of the lake are really nice. You would never know that you are in the middle of the desert :-)
That said, I think when eating here for lunch or dinner, the prices on salad or soup can be quite expensive. When I came here for lunch, I had ordered crab cakes with a salad, and espresso at the end. The crab cakes were delicious, but I found the salad to be just so-so, and not the best value given the price. The espresso was nice. And the service was very good.
I think the unique ambiance of this place really helps it. Its a place I plan to definitely eat out at again.
