Their gluten free buns are really good and not too much of an additional charge (I believe it's $0.75). There's a fairly large selection of burgers and sandwiches you could substitute the bun for, but really that's your only option. Overall, very limited gluten free menu.
Never been to the Black Bear Diner before, but I’d heard raving reviews about it and thought maybe it wouldn’t live up to the hype. It absolutely did, for breakfast at least! I got a meat lovers omelet with hash browns and gluten free toast and I could not get it in my mouth fast enough. The server made sure to check that the hash browns were gluten free with the chef. Husband (not gf) got the chicken fried steak breakfast and loved it.
