Carol, the Blue Bonnet Cafe will be on the right as you enter Marble Falls and shortly after you cross the bridge. It is indeed truly outstanding and very, very reasonably priced. Our friends, who now live out on Lake LBJ near Kingsland (not far from MF) used to live in MF itself. Jim and Lorine tell us the breakfast is equally outstanding. This is a local color place. And a place we will visit every time we are in the area. Haven't tried their burgers, though.
So you'll recognize it... This picture is a bit blurry as we were moving. This is coming from the north. You'll be coming from the south. Parking is around back.
