It's true, everything they offer is GF. We went for breakfast; it was wonderful, and reasonably priced. We had the quiche and a muffin, and sampled the biscuits and gravy; all excellent.
Update 4/22: had lunch there--cuban sandwich, bowl of vegetable soup, coffee cake. All excellent, and my gluten-sensitive wife had absolutely no complaints.
